Slowly getting depressed😩

Well since i found out im pregnant & told my boyfriend stuff been rocky . At first i felt like he was there for me 100 percent .. now its like we are just roommates & i hate it . We barely have sex & when we do , its only because i said something about it .. he barely even sleeps next to me & i cant even remember the last time he rubbed my stomach or back. at this point idk what else to think but he’s cheating 🤷🏽‍♀️ then whn i tell him exactly how i feel he claims it’s because of my attitude.. like im not pregnant on top of going through alot of things physically .. im just real irritated at ths point & ready to be done
