Just for backstory: my partner and me have been having issues for a very long time. I've tried to leave but can't afford to, I cant work more hours or get a better job right now (although I have started an access to university course so I'm trying), I have spoken to womens aid but there genuinely isn't much help and apparently the council can't help without actual evidence of abuse which I don't have.
Whenever we have arguments he constantly swears at me, tells me to go fuck myself, tells me I'm a psycho, that I'm overreacting and that I just don't understand him and always make him out to be worse than he is. I rarely react to those things, I don't use personal insults and don't swear at him but last night I did. I'm not proud of it but I hit my last straw.
Our eldest has a stomach bug, she threw up in her bed and I called and asked for help so I could get her changed, sort the bed out etc. Without waking up our youngest who was sleeping. He was clearly very annoyed with me and I asked him twice what was wrong - the first time he ignored me, the second time he snapped at me to just stop looking at him. I told our eldest that she could sleep in our bed because I needed to keep an eye on her (and I didn't want to wake the youngest up, my eldest sleeps on the top bunk bed and their room is too small for me to make up a bed on the floor for myself) and he made a comment about just going to sleep in his car then. I was trying to deal with a poorly child who was getting visibly distressed at his snapping and I have emetophobia and was trying to keep myself from panicking at the sick myself - so I snapped and said oh just fuck off then.
He didn't sleep in his car, he is still asleep now. I have been up since 5am because now my youngest is showing signs of coming down with the bug as am I. I woke up to a message on my phone from him telling me how unreasonable I was for telling him to fuck off, and that he's sick of me not understanding his side of things and I interrupted him watching a film that he wanted to watch hence why he was annoyed and I never let him explain. I really don't think I'm unreasonable to think our poorly child takes priority over a film! And while I know I didn't respond brilliantly, I think my response was understandable under the circumstances.
