Falling out of love

Hey guys, I’m not sure to really start..I love my boyfriend to the death of me. I really don’t know what life would be without him. I’d say we’re like a pretty average couple, we go on dates as much as we can but we also have a 2yo, we can laugh and hangout together all day. But sometimes he keeps asking for reassurance which I don’t mind giving but it’s like every single day if I kiss him as much as I kiss my son he’d be mad. Even I wake up and give our son a better good morning he’s upset. I try to show him as much love as possible but I feel nothing is enough. I’m getting pretty annoyed and have a hard time being sexual with him.., but then it sums back into I don’t like him cause we live together and don’t have sex everyday. Our sex life hasn’t changed so idk what I’m going through. Idek what I’m asking for. Guess just a rant.
