We have a baby who is 12 weeks old. It’s our first baby. I’m in my late 20’s and boyfriend early 30’s. Last night my boyfriend had a drink with his brother. After his brother had left he began getting upset about his mothers death which happened when he was 19 so quite a long time ago. I told him it was ok to be upset and he said he felt guilty for not going to see her in the funeral home and I told him that was ok and she would have understood. He then moved onto other things and began being very nasty then started to accuse me of having an affair Because I sleep with my phone under my pillow and have it on silent. (This is because he was previously checking my phone during the night and reading my messages, and I put it on silent because I get notifications from games and such) so after this I was crying so much telling him I love him and never considered having an affair so he left even though I begged him not too. He was back a few mins later saying he needed money to get a taxi to his dads. I was so upset and begged him to stay. He went upto bed and is at crying and vomiting because I felt in such a state, Iv been diagnosed with PND and this was really playing up yesterday and I haven’t told him the dr said I have this as I didn’t think he would understand what it is. So when I got into bed I asked him for a cuddle but he said he was too angry. Even though I’d never did anything to make him angry or upset he just exploded out of nowhere. I feel so sad and down today and he hasn’t said sorry but tired to act normal with me. I don’t know what to do. It’s not the first time he’s done this to me and I’m beginning to think it’s not normal to want to make your girlfriend so upset like that and to go checking her phone when she’s asleep. How can I get out of this mess without leaving him? Will it get better?
