We haven’t kissed or had sex in three weeks

Whenever he comes over, which isn’t often, he doesn’t kiss me or initiate sex anymore. I am 2 months pregnant and I just want some affection. I asked him to come over and he said “I don’t feel like paying for a lyft” so I guess that’s where we stand. He’s never had a problem walking to my house before. I can’t walk to him because I’m pregnant and not feeling the best. How do you tell someone you want them to kiss you without sounding clingy af? I can’t really initiate it either because he’s weirdly distant. He doesn’t really get close to me and when we are close, he like turns his head almost so that he isn’t actually close to me. I’m feeling really stupid and ugly and unwanted.
