Am I think to much in to it

My boyfriend and I have been having rocky relationship for about at least 6 months. We love each other so we been trying stick though. Recently everything has been great. He even bought me home flowers yesterday. Everything great but when he come to bed he seemed off. He was just playing games on his phone. When it was time bed he had me lay on him but just whet bed we normally talk first. ( even when we were rock) am I just thinking to much on to it?
