We are not in love

So I've just came to the conclusion that I don't think me and my boyfriend are in love with each other. He's so unaffectionate. He never touches me or hugs me or kisses me or anything. I'm 4 months pregnant and I feel like we should be getting closer but I feel so disconnected from him and it's really starting to bother me. I don't feel loved or wanted or even liked half the time and it's so hard especially now that I'm about to have a baby with him. I don't want to waste my time anymore if we're not going to make progress and I'm just so confused and don't know what to do. But I honestly don't think there's someone else. I don't believe he's cheating on me I just feel like we're roommates and nothing more
