I feel like my boyfriend isn’t attracted to me anymore :(

Recently I’ve been feeling like my boyfriend and I are falling apart. His mom doesn’t like me & for what reason? I honestly do not know because I do not converse with her, but I do always show her respect “good morning, afternoon & night & if I go to any store I always ask her if she wants anything, but she will never seem to like me” and at this point I’ve gotten over it. But, my boyfriend is now starting to pull away. Although, I don’t believe it has anything to do with his mom. He’s pulling away. We used to have sex 3-4 Times a day & now he doesn’t want to have sex once a day. He shows me no attention, he’s starting to act like he doesn’t care anymore. What should I do? Am I being too dramatic? Am I overthinking this?
