Relationship question

So I feel like a crazy girlfriend, recently I’ve noticed my boyfriend will go hours without replying to me but I’ll see things he shared on FB in those hours of not talking to me. It makes me feel a pretty ignored. I get pretty upset and I usually confront him about it which just upsets him. He’s also been unusually loving towards me, we’ve always had a fairly loving relationship but recently he seems to have gotten pretty protective over me, and he kisses me more and touches me more, like playing with my hair or running his fingers over my cheeks. I love the new affection but I can’t help but feel suspicious over it. I feel awful for feeling this way over him being more affectionate. Am I crazy?
