Husband choosing not to be around entire pregnancy. 😒

Would you be mad husband is leaving the last 4-5 months of pregnancy & only showing up before the baby is here? He has the choice to move to California with me & find a job out there but he rather move back to Texas (his family is there). I only known them really 1 month in the last 2 years . Plus the step dad is an alcoholic and his mom likes to drink too. His siblings are 16 & 18 and they are spoiled brats who don’t respect their elders and have an attitude. Literally call you a bitch ALOT and think it’s a joke. They stayed with us recently and he got into a huge fight with his mom over how she doesn’t step up and tell her kids to not talk like that. I had enough of their stay bc of it. Where he is staying is a small town so not much to do but party & drink to have fun. I rather move to CA to be with my family bc they have been supportive my whole life (not his mom especially step dad to him) and with bringing a baby into the world I feel safer and less stressed being around my family. We were going to split ways back in May and found out pregnant in June. I’m now almost 13 weeks pregnant. We want to try for the baby and stay together but him making this decision hurts. We are his family and I never wanted to be pregnant alone especially in the 2nd and 3rd trimester you would want your partner there. Am I wrong I feeling like this? I tell him I respect his decision and happy for him but I don’t think I’ll want to stay with him after that. I feel vulnerable as it is and I feel his decision is selfish. He should be my support not my parents stepping up bc he chose to not be around. Being long distance for the next 5 months doesn’t sit right with me. He will miss baby shower, the holidays with my huge belly bump. And what about when I have late night cravings ? Or huge feet and need a little massage? I always expected my husband to be around for this. A support. In this together.. It’s so easy for the man to walk up and leave like that and me being pregnant I can’t just get up and leave so easily.
