There is a difference between being private and being kept a secret 🤬

I’m still so angry about what happened last night. My man asked me to go to his going away party. We used to work together n I was like u sure? I’m 13 weeks pregnant with his baby. It’s my 6th pregnancy so I have a small belly starting. I had to find something to wear that was loose and flowy because he didn’t want me to look pregnant. I really wanted to ware a certain dress and he said “u can’t ware that it shows ur pregnant” so I find something to ware. Well we go I don’t touch him I act like I’m his friend because he always says he likes to keep his business private. Ok. Cool. W.e I don’t need to be all over him 24/7. Well his roommate saw us and he invited him over to the table for dinner. Fast forward to going home we took separate cars, I made it home first and hoped in the shower. He came in so angry. Like so angry. And he said “why the fuck did u lock the door?” And I said “because? I am in the shower and I’m home alone?” And he said “so?!!” “So I locked the door” and he ignored me. I asked him if he was ok. And he said “no I’m not fucking ok! My roommate is spreading our shit to my coworkers. Im fucking pissed the fuck off. This is absolutely bullshit. As soon as ur there that’s all that happens” I very quietly apologized for going. And he said “everyone doesn’t need to know about u n me!!!” He stormed out left for an hour, he came back and tried to have sex with me to which I told him I’m too tired. N he went to bed. Im so angry. He’s never made me feel like a dirty secret in my life. It’s like he’s ashamed of being with me. We have a large age gap. He’s 44 and I’m 26 but Jesus Christ… wtf did I do wrong? I went because he asked me too….
