I once had similar feelings about my boyfriend at that time (we're married now). I thought his constant attention and care was either fake or smothering. I wasn't sure if I liked it or not. So what did I do about?
I looked up actual cases of smothering and control. Most of which were stories, blogs on the internet. And I had friends that had histories they loved to talk about as well. I looked at the constant symptoms that those relationships all had in common and compared them to what was mine. And found them not the same. In fact, I found my boyfriend's ways sincere and sweet.
Of course, there may always be some degree of expectation. I'm glad to say that I did my best to be objective. That's something one can only decide for the individual; that border between the reality and fantasy, when combining another and yourself. And the deeper that relationship goes, the tougher it will get. This is not always a bad thing, it shows a growth.
