DON't KNOW WHAT'S HAPPENING TO ME 😩😩😔

So, I love my boyfriend and trust me I love him but lately I've been feeling like I don't Santo to have sex with him it's like I don't find him attractive anymore and I just don't get turn on. Last night we were trying but I just couldn't and he said " hey it's fine babe, that's normal sometimes you just are not in the mood" so we watch tv and went to sleep and he was really sweet like always, but it's been almost a month and I don't know what is wrong with me. Should I tell him or should I try one more time ?? Please help 🙏🏻🙏🏻
