Advice needed 😭

I've noticed that my boyfriend and I have kind of drifted apart since becoming pregnant so last night I took a shower I put makeup on I put a not sexy but not just plain outfit on for him before he came home from work and he gets home there and he doesn't say anything he opens up his box that he received in the mail with his new car parts and then decided to go to the bedroom and play xbox and be on his phone till 3 a.m. . he didn't even say anything to me about what I look like didn't kiss me or hug me. I feel like I'm not filling his needs the way I should be I feel like he doesn't find me attractive and it really hurt my feelings because I'm so self conscious about the way I look already. what is some advice on how to cope with this and make things better. I dont feel good enough. I noticed he has been spending more time on porn sights than with me. Is he cheating? Am i just not attractive enough for him anymore?
