i need advice

me & my ex was working on getting back together i just happened to get pregnant in the process . one sec he wanna be with me and and have our " family " next thing he switches up & its the opposite so im like enough is enough im done with the games we can coparent ill see u when im going into labor he has brough me through hell and back this entire pregnacy and im done being sad about our relationship failing cause clearly im the only one whos putting in the effort everyone can see it. The issue is i felt like i been in this pregnancy alone he just started coming to the appointments so i see him at the appointments which is once a week now we dont talk to eachother at the visits nor do i dont talk to him during the week no texts no phone calls nothing he dosent care to check up on me and see how im doing so am i wrong for saying i went through this pregnancy alone? i had to go to the ER twice or 3 times he was there all expect for one. am i expecting too much?he swears he been by my side i say otherwise
