Feeling unloved

My boyfriend and I aren’t anything like we were before I got pregnant. We used to go do things and spend time together and have a lot of sex and showed affection to each other constantly and now it’s a struggle to get a a hug or “peck kiss”. We’ve only had sex maybe 3 or 4 times since we found out in July and those times were basically quickies and now he’s been sleeping on the couch the past two months. He says he’s stressed out but it’s really getting to me, I’m up crying and he’s sleeping on the couch with the dog that he gives more attention than he gives me😭 I just hope things go back to normal after I have the baby. I love him so much and I miss how we used to be. I hate not feeling wanted it’s like he doesn’t love me anymore.
