Crappy husband

So I am currently pregnant. I need to get this of my chest. I am currently 4 weeks. Just found out over the weekend. So this is the deal. My husband and I have been having a hard year for our marriage. He is very stuck in my past, I had a previous long term relationships before him . He knew about it before getting married to me. Well due to this he started talking to other women and sexting which I found pictures. This was a whole as problem. Fast forward, the lady is in Mexico. My husband has very crazy thoughts of cheating on me and blah blah blah. We planned on going to Mexico in December for Xmas. Well I knew my fate. But now I found out I’m pregnant. I have a history of ectopic pregnancy and miscarriages. I told him about the testing this morning for hcg and ultrasound and he sounded pissed. So I texted him saying if you want to go to Mexico by all means go visit your parents like you want to I’m not gonna stop you. You don’t have to be mad. His response was. I am not mad. I just can’t believe when we are planning on traveling to Mexico you become pregnant when you haven’t been pregnant in a long time so I’m bawling my eyes crying because my pregnancy is an inconvenience for him and I told him I can’t believe you’re mad because of that his response was no, but I just don’t understand so what do I do leave? It’s not easy to stay it nor to leave. being married is hard.
