Valid feelings? Pregnancy hormones? Or overreacting?

[KindOtter]

Myself (26f) and my partner (28m) have had quite a roller coaster of a relationship since we got together in 2020.
I’ll try to put a long story in short terms.
he broke up with me a month after our son was born in 2024, I had to move back into my parents house with our newborn son. We then got back together 3-4 months later but we wasn’t together very long because I found out he had slept with someone else while we was broken up and then lied to me about who it was so I broke up with him. We then got back together 6-7 months after and everything was going well and smooth so we decided to try for another baby because we wanted kids to be somewhat close together in age.
i am currently 29 weeks pregnant with a baby girl and my son is 2 years old now.
this pregnancy has been significantly worse. My mood swings have been crazy, and generally feeling unwell/exhausted a lot of the time. I ask my partner to help with either house chores or looking after/entertaining our toddler so I can catch up on the housework. I am a bit of a clean freak and absolutely HATE clutter so I start to get a bit irritated if there is a lot of crap just laying about (toys not included)
whenever I ask him to do anything, unless he does it straight away which is highly unlikely, it doesn’t get done he always says “sorry I forgot” and I feel like I’m always picking up after him or cleaning his mess.
I also feel like he doesn’t love me romantically but just wants me to have sex with me because he doesn’t do anything romantic or at least it’s very rare.
theres a bit more too it as well but I think I’ve explained enough.
am I overthinking/overreacting? Could me feeling like this be pregnancy hormones? or is it completely valid feelings?

He sounds rubbish and now you’re tied to him with two kids because you wanted them close together 🙄
I’d be prepared to be a single parent long term - I’m sure you are anyway
he’s lied, cheated and pesters you for sex whilst not being a partner - he’s does that because you took him back and he knows you will forgive him
I bet he’s a shit dad too
Do you work? Have any money/access to benefits
you’re so young and have a lot of life ahead
don’t spend it with him (and you have no financial protections as you’re not married)
Start to build a really good life for you and your kids away from him

I would say it’s your common sense kicking in belatedly and telling you that you picked a dud to have two children with, and that you should forget the relationship and focus on establishing yourself financially and working out an amiable co-parenting relationship for the future.

I currently don’t work, although I do want to go back to work but that won’t happen until sometime after my girl is born. I’m on universal credit so get help that way plus he pays me money every month because I deal with all the bills and food shopping but in my opinion he doesn’t pay enough as it isn’t even 50% of the bills and food shop.
I feel like a single parent most of the time and when I was a single parent we couldn’t communicate nicely/civilly enough. I love him and want to make it work for the kids if nothing else but I’m not sure how long I can continue like this as I feel like there is no respect. Whenever I have tried to leave him, he always says things that make me think I’m being the unreasonable one so then I just end up apologising.
I am super nervous for when this baby arrives because my support system is not great tbh, I don’t have any siblings and although my parents live round the corner their health is not in the best of way so they can only look after my son/kids rarely and not for very long

You’ll cope a lot better without him and his moods etc weighing you down
You don’t have to make the relationship work for your kids - in fact don’t do that

Thank you
