DH and I have been married 3 years. We have a daughter who is 14 months. In most arguments, if he feels like he's not 'winning' or doesn't have a valid point then he threatens to break up with phrases like "I think we are done" "I've had enough of you, I'll be better off without you" "that's the last straw, I'm moving out tomorrow morning".
The things he says it to are just trivial arguments that do not need to be escalated to break up level. For example earlier today i got annoyed at him for putting an open bag of M&Ms into my bag without closing it, it melted and would have ruined the bag had I not noticed it. I angrily told him to think before doing things and to be more careful with my belongings (no curse words, no shouting, literally just that in an angry tone). He said he's fed up of me talking to him like that and we are done (I don't get annoyed unless he does something silly like that).
Or if whilst we were trying to conceive no2 I got annoyed when, after promising me to not drink more than 3 drinks per week as our fertility doc advised, he said it's actually up to him and if he wants more he will have more. And if I complain about it he will 'get me out of his life'.
I don't want to run after him every time he threatens and in all honesty I'd be ok with losing him... but I am terrified of being separated from my daughter and not see her every day.
On other occasions he's super loving and he called me 'worlds best mum' yesterday and told me how lucky he is with me. But in arguments he can be hot headed and make threats. He's so hot headed he could actually leave.
Anyone with experience of not seeing babies this young daily, in case he does leave and we have shared custody? Anyone with experience of threatening partners? He was not at all like that before marriage.
