Ex-H having baby with woman he has apparently been seeing for 3.5 weeks

utterlygobsmackedrightnow · 19/11/2025 21:50

Here is the background:
Ex-H and I were together for 12 years – the last few years weren’t great. We had periods of relationship counselling a few times, the most recent being between July – November 2023, at which point we agreed the relationship was over. We continued to live together as though we were still a couple until summer 2024 as we didn’t want to negatively impact DD’s exams. H then moved out and DD and I stayed in the family home until June 2025 when we sold it and moved. Divorce has just gone through. DD off to uni. Everything has remained reasonably amicable and we share care of the family dogs so see each other for a quick dog handover most weeks and occasionally a cup of tea. I tried really hard to make our marriage work over the years but he never put the same degree of energy into this that I did – lots of conflict over mental and practical load, family time, him putting his needs, wants, hobbies, work etc. before everything else – the usual. (Should also mention that he is DD’s stepdad, not bio dad, been in her life since she was 4).

This week:
Ex-H drops off the dogs last Friday and stops for a chat. He mentions that he has started seeing someone and thought he should tell me – that’s fair enough, we’ve not been properly ‘together’ for 2 years really as we agreed to separate in November 2023, and I imagined it would happen at some point and am very happy to be single and free of him. Then he says he first met her though a work thing in September 2023, but wants to make it clear that they didn’t meet again or date until October 2025, just a few weeks ago. This seems to me like quite an odd thing to say – why would he need to say that? Hmmm. Spidey senses kind of tingling, but fine, whatever – it’s all the past now.

Today:
He drops off the dogs AND TELLS ME SHE IS PREGNANT AND THEY ARE HAVING A BABY. I express almost comedy levels of shocked surprise, followed by quite a lot of WTAF and does he seriously expect me to believe he is having a baby with someone he apparently didn’t date until the end of October??? He gets out his laptop to show me the email she sent him on 25th October asking him out for a coffee because he wants me to believe he is a decent man and telling me the truth. So let’s say that they went out for coffee 25 days ago, and had sex that day at the very earliest, she’s apparently pregnant now and they are both delighted???

This is insane, right? He genuinely expects me to believe that this has all happened since the 25th of October and that there was no relationship whatsoever between them previously. Does he think I am the stupidest woman in the world?

He’s 55, she’s 36. If they are actually having a baby, he’ll be 60 by the time it goes to primary school, and 74 when it goes to uni.

I don’t care about him meeting someone else, I sure as hell don’t want him – but I do care about the idea that there has probably been something going on since we were still together and he is lying to me though his teeth. I hate being lied to more than anything – it is treating someone like they are utterly stupid and beneath you. I hate the idea of completely losing trust in someone that I spent a long time with, and that is still part of my DD’s life. I am wondering if the bullshit cover story is actually because he doesn’t want my DD to hate and disrespect him, rather than giving a toss what I think of him. This is a man who really likes to think of himself as decent and honourable. There’s no chance this story is real, is there? It’s like the rational part of my brain can see it’s ridiculous and expecting me to believe it is quite frankly insulting my intelligence, but there’s another part that wants to believe in the ‘decent and honest man’ persona and can’t get my head around the idea that he has been lying to me for probably quite a long time, and is not the man I thought he was in any way, shape or form.

(BTW when I have ever read anything like this on MN I have suspected it was probably made up nonsense because it’s too ludicrous to be real, but this has actually happened to me this week, so I apologise to anyone I ever doubted because apparently this shit really does go on, in fairly normal people’s lives. And then I always wonder why people would immediately write about it on a random forum but I am still trying to process all of this and interested to hear what other women think, I guess.)

Also, 1. Your DD should cut off contact with him, he’s not her real dad. She’s an adult & taking responsibility for her own life. What will they talk about? His excitement of starting a new life & baby that your DD has no connection to? 2. Don’t beat yourself up with conception time, lies etc. He’s your ex, move on. Forget him. 3. It’s not healthy having any sort of ongoing friendship or relationship with him. Take his dogs to the rescue pound so they can be adopted by someone else. Then you never have to see or speak to him again. Problem solved. Move on. Stop contact. In any event, his new partner will soon order him not to visit you or give you money as she will need his money herself.

Are you the new partner?!?

“Does he plan to maintain a parental relationship indefinitely, or phase it out?
I suspect it will change drastically as the pregnancy progresses and when the baby is born.”

Why would his new partner object to his continuing to be a parent to a step daughter that is already old enough to be at university?

I didn't say his new partner would object.
She might, though.

He’s your ex. Why do you care? He doesn’t owe you anything. Also, why does he owe your DD anything? He’s not her real dad. Your DD should be more interested in her real dad. Your ex took you on with someone else’s kid, so it was always some ticking time-bomb he would run off, or want a kid of his own. Guess what? He’s done exactly that. Good on him. You’re overjoyed about your DD, now your ex can also be overjoyed of a kid of his own - with someone else.

He was her father figure since age of 4.

Nicewoman · 20/11/2025 00:45

Mumtobabyhavoc · 20/11/2025 00:37

how does that have any bearing?

Because the guy ran off to have a kid with someone else. Just she isn’t told that, naturally, as the ex owes her nothing.

Why do you care what your ex is doing now or in the past. They are your ex for a reason.

She cares he's making her out to be stupid, she cares he's not the man she thought he was.

she possibly cares that she thinks he's too old to be having a child (and I agree) for the CHILDS sake.

Samethingtwice · 20/11/2025 00:49

The man took on a child who wasn’t his and still pays for half the dogs/cares for them. You’re divorced? I’m sure it was a shock but he’s about as decent an ex as you could ever hope for. Honestly just wish them well and let it go.

Francestein · 20/11/2025 00:52

I suspect he’s lying about how long they’ve been seeing each other, or he’s just a convenient, gullible schmuck who has been chosen to raise someone else’s baby. Either he thinks you’re stupid or he is completely unaware that a pregnancy would only just be detectable in that time frame.

Ohnobackagain · 20/11/2025 00:55

@utterlygobsmackedrightnow wouldn’t be surprised if it IS true and he doesn’t want to let on that he is now bricking it. I’d tell him calmly that you don’t believe he only started seeing her this year though; say it doesn’t matter now/all water under the bridge but you’d prefer honesty. Then wish him luck. Do you really want to be in touch though? Do you want to share the dog? I’d consider not being in contact and leave it to DD to decide if she wants a relationship (whether you do or don’t) …

Also just to say that I’m not looking to meet anyone else myself - I’ve reached a stage in my life where I’m happy on my own and have zero desire to complicate my life with another bloody man! I’m free!!!

Hmmm

I'd start thinking about how to make it affordable/doable (with work) to keep the dogs all by yourself.

No matter what he says now, I doubt it'll continue once she's had the baby. Pussibly not his contribution to DD either.

i understand how hurtful it is that he's lied & that he isn't the man you thought he was. But yeah try to focus on your freedom!

Nicewoman · 20/11/2025 01:01

BrooklynCroc · 20/11/2025 00:37

Are you the new partner?!?

No, but having contact with her ex for 2 years after the split is harming her ability to find someone new. It’s her exes dogs, not hers. And he’s not paying the full upkeep for them. Also, even if she didn’t want to meet someone new, she is getting upset & angry, depressed and over-analysing lies he could have said or might be the truth. Instead of all that wasted energy, she could be happy & zen. Seeing the dogs every 2 weeks or whatever is the wrong way to handle things. She and her daughter need to cut contact immediately and move on. Besides, the new woman pretty quick is going to demand the ex cuts contact, so either this woman does it on her terms with dignity, or she will suffer & be told the same by her ex, which would be more humiliation. Her choice. As posters say - he’s your ex, move on. Forget, cut contact. Start again. It’s just not mentally healthy keeping in contact with exes, unless you have small kids - and they don’t in this case.

JFDIYOLO · 20/11/2025 01:04

Either

1 He's lying, or

2 She is and he's not the father.

Whichever ... It's none of your business. Turn round, walk away, build an interesting life for yourself and stop obsessing over theirs.

It's DONE.

He’s 55, she’s 36

Ahh... Men. Smh

I didn't say his new partner would object.
She might, though.

How does his new partner feel about him maintaining a parental role with her?

Apologies. I thought that was what you were asking when you asked how does his new partner feel about him having a continuing parental role with his step daughter.

DallazMajor · 20/11/2025 01:31

Let him crack on. Don’t waste an ounce of time pondering the finer details.

OriginalUsername2 · 20/11/2025 01:36

Bullshit.

Even the fastest possible timeline (ovulation perfectly timed, implantation, rise of detectable hCG) takes 3–4 weeks and most women don’t test until they’ve missed a period.

Octavia25 · 20/11/2025 01:55

Oh well, that’s his life over 😆

I didn't cover all the possibilities, but it is a valid question, isn't it?

Seriously, your post was very rude.

VVM · 20/11/2025 02:03

@FrancesteinYou are clearly the one unaware of timings and when a pregnancy can be detected. If they met on the 25th October and had sex and it was her fertile window it would put her around 6 weeks pregnant presuming her period was 2 weeks prior.

It does happen. I hadn’t had sex for around 8 months and then ended up doing so with someone one time, one night and then 2 weeks later had the strongest positive pregnancy test. I was in my fertile window obviously and it took one time of 2 mins. Why does this need explaining? Mumsnet is full of women testing at 8/9 dpo, getting positives by 10dpo and then there’s a minority like you who believe it’s not possible to know you’re pregnant at 6 weeks.

Nicewoman · 20/11/2025 00:45

Maybe it was unintended?
Could be a lot of reasons. 🤔
But if you wanted to posit possibilities it would've made more sense to state your theory up front.

VVM · 20/11/2025 02:08

@OriginalUsername2 I had sex one time on one night and then 2 weeks later got a positive pregnancy test. How is it impossible? A lot of women get positive pregnancy tests at 10dpo. So presuming she was ovulating around the 25th October then she could have found out she was pregnant nearly 2 weeks ago.

SallyDraperGetInHere · 20/11/2025 02:25

IMO he’s reverse-engineering the news, and don’t be surprised if the baby is born ‘early.’ I suspect the email is somewhat contrived to fit just-about-acceptable dates. He’s got in early with the news, and at least you are forewarned, but I strongly suspect the dates. That said, he’s brought you the news early, and you’ve time to sit with it, but it nonetheless remains dubious timing. Best rid; process; flowers 💐

Muffinmam · 20/11/2025 02:26

Why didn’t you have a baby with him?

It sounds like he wanted to have a child of his own and the reason your relationship failed was because you couldn’t give that to him.

You need to understand that your relationship is over and sharing dogs is utterly ridiculous. They aren’t your children.

You can expect him to completely pull away now. He will be a father soon and won’t have time for you.
