Guy trouble

Hi guys. So me and my loved one have been together for 10 months.. I love him and he makes me happy. We even live together, we are super close. But you know how it is.. The beginning of relationships are all lovey dovey and sweet but then that kind of dies off.. That's what has happened. But I met this guy through some mutual friends at a haunted house that I went to without my boyfriend. I didn't cheat or do anything wrong but we just sat there and talked all night, he bought me hot chocolate and hand warmers and it just made me feel good Inside. He was really good to me and so sweet. I feel guilty for even thinking like this but I wish my boyfriend would do the simple things like that to make me happy... Am I wrong for feeling this way?
