Long story short my partner and I have 2 children aged 1&2.5years. Things were bumpy with him being present and failing to get out of bed and be a parent basically. To the point my parents noticed and we only see them 2 times a month. During my second pregnancy he stopped working nights when he got a new job and things got better.
I wasn't concerned about things being bad again until about 6 months ago. We began arguing more and a lot of the time we ended up spiralling into lots of tiny disagreements that exploded into big arguments. I've began to notice that his behaviour towards me has taken a turn in terms of raising his voice at me and calling me names. Also that in every argument I find myself apologising and saying it's my faulty when I don't always believe that, he hasn't ever apologised or taken responsibility for anything even when he doesn't wake up (which is happening again, even on school mornings for our daughter).
When he is home he is constantly complaining about the fact our children have toys out or small things that every household with children have (minimal washing up, laundry and toys). I do my best to keep it clean as my daughter who's just turned one is still heavily relying on me with breastfeeding, she was born early and has allergies so its a little tough on me and her as I have anxiety which flared after her birth. We are due to get married in December (was meant to be September but I wanted to push it back due to things not feeling right) when I asked this to happen he made me feel like I was awful for wanting it. He using cleaning a way to not be around the children in feels and they've started to notice and neither of them want to go to him.
I have also noticed that when we have sex we don't argue as much and that he's asking for it every day, I have had a really low libido since our second daughter was born and have tried to help it but I'm struggling. He has recently taken to telling me that my body belongs to him too and even after telling him I don't like it he still grabs at me constantly. I was a victim of SA before we got together which he knows and says he respects my boundaries but I am beginning to feel that he doesn't and that maybe things in the relationship aren't okay.
