I've been exactly were you are before. Although, I thought I wasn't giving my boyfriend enough attention. It's not you. A guy's mind can be like a fish. Here one minute; gone the next. He may not realize that he's being distant or unaffectionate. Talk to him about it. Nothing can go wrong if you just state how you feel about something. If talking doesn't work hide or get ride of everything that he could get distracted by.
