I was the "other woman" in my own relationship

InvisibleWoman88 · 08/05/2026 09:20

Hi everyone, I’m in a very painful situation and really need some outside perspective.I was with a man for a long time. In the beginning, he made me feel like a princess. But over time, the attention faded, and I caught him talking to other women. After a big argument over my "jealousy," he dumped me. I was devastated and blamed myself for being too insecure. I chased him for months, crying and even going to his door.
Whenever I went to see him, he would kiss me and tell me, "I need you, I will never leave you." We would hug, and I’d go home feeling hopeful. However, I noticed on social media that he was always out, but he never posted the girl he was with, claiming she was just a "close friend."
One day, I went to his house and found a birthday card that said, "Happy 2nd Anniversary." That’s when the soul-crushing truth hit me: he had been leading a double life, dating both of us at the same time for years. When I confronted him, he coldly said, "I chose her for marriage."Despite this, he asked to "stay friends," saying he couldn't talk to her the way he talks to me. Because of my deep attachment and trauma bond, I stayed. But every time we met, it turned physical. To him, I became a "fuck buddy," but I am still deeply in love and trauma-bonded to him.He is now planning to marry this girl, yet he still sends me explicit sexual messages and meets with me. I want her out of our lives. If I tell the girl she is being cheated on, I’m afraid he will just tell her I’m a "crazy, jealous ex" who won't leave him alone, and she might believe him because.Now, I am considering telling the girl’s family. I want to let them know that the man their daughter is about to marry is still seeing me and sending me sexual messages behind her back.Is telling the family the right move? How do I handle a man who uses my love to keep me as a secret option while he builds a life with someone else?Any advice would be appreciated.

Yep, tell her and her family. Show them the texts/ messages. She has a right to know and so do they. And you'll have the extra satisfaction of ruining his plans.

Tell her and her entire family print off all of the message and post them to everyone she deserves to know. Then get yourself therapy

This precisely
if absolutely want to know

but why on earth did you ever think this was a good idea???? Baffling

notatinydancer · 08/05/2026 18:36

You’re not the other woman in your own relationship. You’re the other woman in someone else’s relationship.
He told you they’re not sleeping together ?? Sorry but were you born yesterday? Of course they are.

I could never hurt him.I love him,and I love the time we spend together;I feel a sense of peace when I’m with him that I can’t find anywhere else.I want him to be happy.Of course, there are moments when I think,'He made me so miserable,I wish he could feel this pain too,'but I would never act on it. I’m not capable of doing anything to hurt him.Just knowing that the day will come when he marries her is already agonizing.I don’t even know how I’m going to survive that day.The thought of it alone is enough to break me right now

I knew it was a disaster from day one.But I let my feelings override my logic,and once I was in, I didn't know how to get out.It wasn’t a choice made with my head, it was a trap I set for my own heart

Just read back what you’ve written……

nobody “sets a trap for their own heart” that’s the most ridiculous statement

you now need to get yourself sorted out and have some sort of counselling and definately do the right thing and tell the other woman she deserves to know - you’d want to know if you were preparing to marry someone.

You're wasting your best years on this ridiculous situation.

You're going to look back on this with so many regrets if you don't start getting a grip on your own life.

Stop wasting your time being some bloke's dirty secret. Get away from him, get therapy, meet someone new who wants you above all others.

Sprinkleofspice · 08/05/2026 18:49

What was your childhood like? I can understand being heartbroken about this situation but still loving him after all this (especially the BS about his girlfriend being a virgin) is a surprising response

LadyVioletBridgerton · 08/05/2026 18:53

What’s so great about him? Has he got a 10 inch cock?

Sunshinemoonlightboogie · 08/05/2026 18:53

Ok, this is context, you sounded young and this helps us understand!

I was an absolute idiot at 31, fell ‘in love’ with totally rubbish men, couldn’t see the wood from the trees, cried endlessly.

I learnt a valuable lesson, love is NOT what you describe. Love is a verb, it’s action based and it’s between two people whose actions show compassion, empathy and kindness towards each other everyday.

What you’re experiencing is obsession/addiction, it’s toxic and it’s holding you back from finding happiness and future long term happiness.

You are stuck in language that is keeping you hooked, all this trauma bonded nonsense and this idea that you’re at peace when you’re with him. It’s hits you’re having not peace.

You're behaving like a drug addict and addicts need to go sober. Believe you and me sober up from this utter loser and you’ll get the ick you ever let this nasty piece of shit anywhere near you!

Seriously, I’m older and wiser but I’ve learnt the hard way.

TheZTeam · 08/05/2026 18:53

I don’t understand why you’re even entertaining his shit. He’s not giving two hoots about you or the fiancée.

find your backbone missus and get rid of him. And get some therapy because you’re being taken for a fool, and you’re ruminating so much and building it up to trauma bind, hes wonderful, I love him I can’t let him go - where if you had more self esteem you’d have binned him off long ago. I wouldn’t entertain someone like him for 5 minutes and the instant I found out I was the other woman he would have been toast.

but it took me a long time to get to this point - I had a shitty marriage, and did therapy after so I didn’t make the same mistake again.

all the best op.

This is not letting her know.
This is punishing an innocent woman with public humiliation.
She will already be traumatised.
Her fiance cheating is her private relationship, she has already had her agency removed by this man and now you're suggesting OP does the same.
The only truly innocent party in this shit show is the fiance.
Inform her, fine, but for God's sake keep her family out of it.

And get yourself off to the std clinic just in case.

I agree, I would want to know the truth too. But there is something chilling I need to share. He once told me about a woman who supposedly 'obsessed' over him, followed him home, and begged for a relationship. He even claimed she was married with kids. Now I realize he was probably planting a seed in my head so that if any woman ever contacted me to warn me, I wouldn't believe her.
He has likely told his fiancée the same story about me—labeling me as 'the obsessed one' to discredit anything I might say. He has her Instagram password and total control. He has only shown her his 'perfect' side and made her happy. Part of me thinks I shouldn't ruin that happiness, but another part wonders... don't women eventually feel it when they are being cheated on? I am so conflicted

PerryMenopaws · 08/05/2026 19:07

Op...

This isn't at all what love feels like. What you're describing sounds like obsession. People might use different fancy words for it but for some reason you've tied your psyche to the completely false belief that if he just loves you then you'll be okay.

Tough love...

If he ever did decide he wanted you and only you (which he won't) then he would still be a vile, lying, misogynistic, abusive prick and your grand prize would be a pile of sick.

He treats you like you're nothing because you accept it. Abusers can read the room. He knows you will take it, so he keeps giving it. The only way he'll ever respect you is if you tell him to fuck off and mean it.

This really, really, really is NOT what love feels like. If you love people then yes being with them makes you feel comforted and happy but in your case it's more like relief.

If a loving partner shags other people or said he wants to marry someone else, it would be completely repellent.

Love moves freely in both directions. You can't force it, persuade it, manipulate it, or eliminate competition to get it.

Every minute you waste on this is a day of your life you're not living for your best interests. There's no possible outcome that's good.

You need to cut him off cold turkey. Completely. No friends. Change email. Change numbers. Move if you have to. You're perpetuating the cycle.

You are also not a victim here. You are knowingly pursuing and having sex with someone else's partner. Please stop.

Get support IRL. Also look into RSD or BPD as you seem to have severe emotional flooding and you might be looking for relief. Please get support 🙏

I grew up with a father who didn't love my mother and was constantly violent towards us.He was the kind of father who silenced us every time we tried to speak and never listened to what we had to say.
Looking back, I realize I grew up in an environment where 'love' was something unpredictable and quietness was survival.Maybe that’s why, when this man gives me even a little bit of attention or 'peace,' I cling to it so hard, even when I know his words are lies.I am realizing that I’ve spent my whole life being silenced, and I’m still doing it to myself by staying hidden in this relationship

I don’t want to humiliate anyone. My concern is that the fiancée is just as emotionally attached to him as I am. I’m afraid that if I tell her directly, she will simply think I’m making things up to ruin her happiness and will label me as a liar.My thought about involving her family—perhaps just her mother—wasn't to cause a public scandal, but because I thought they might be the only ones who could actually protect her and stop her from marrying him. I feel like she won’t give up on him on her own.But I am so torn. I don't want to cause more trauma, I just don't want another woman to end up in this trap

I don't want to humiliate her in front of her circle.I just want her to take this step knowing everything.Even if it’s not me, this man will cheat on her with someone else.If she accepts being cheated on, then she should accept marrying him.I just know that she sees him as a 'clean,' perfect man, and she deserves to know the truth before making a life-long commitment.

YOU and him are humiliating her already by carrying on the way you are! You don't have the moral high ground here. How do you know some much about her and her last relationship and how she feels now? That's just weird and creepy.

You want validation and closure. You’re not going to get that. The strongest message would be grey rock. Silence.
