Feels like bf doesn’t love me

Currently 17wks pregnant, been living with my bf for about a year now and been a thing for a year and a half. He never shows that he loves me. He won’t kiss or cuddle or hug or tell me he loves me. Although he has no problem saying I love you when he needs something. For example today I went to my friends fathers store to get some food and asked if he’d come in with me. He said he’d rather wait in the car then told me he loved me, but it sounded really condescending considering I was going in to get food for him only. I’ve brought this up in the past and he changed his ways for like 3 days then went back to being salty and distant. It’s honestly pushing me away and I’m starting to feel like I’m falling out of love with him because of it. I feel like I shouldn’t have to beg to be loved. I just don’t know what to do anymore. He keeps blaming it on stress but it’s been like this the whole relationship. I just want my boyfriend to act like a boyfriend and not just a friend.
