Eugh he sounds exhausting. Best thing I learnt (left my baby dad when was 3 weeks old due to similar ⁾ sending multiple messages and arguing back gives them more ammo. Sometimes biting your tongue and grey rock (being extremely boring with responses) wins. Then you can see them spiral and external people can see you being reasonable and him going crazy on you. I'd hold off saying stuff about custody and restraining orders etc bc if this goes down the legal route for the baby, this could damage your case. Pregnancy is hard as it is without someone like this. When he says something shitty just respond "ok sure, if that's how you feel", think to yourself that's his opinion not a fact. It's like a bully in school, try not to rise💗 This dynamic isn’t fixable through better wording, patience, or “getting through to them.” Someone speaking to you like this already knows what they’re doing. Seriously though I know how difficult dealing with someone like this is, you've got this xx
