getting paranoid...

I have been together w/ my boyfriend for about 3 months now...and it always takes me a while to fall for a guy. Well, I've finally fallen for my new guy, and its hitting me hard!! I'm so afraid I'm becoming overbearing, especially because I guess he's used to me being a little more 'cool.' The last time I was in a serious relationship the same thing happened...the guy liked me more than I liked him at the beginning...then I finally fell for him and I ended up liking him more than he liked me...and then it ended. So, I'm getting paranoid the same thing is gunna happen again! Has anyone been here before?
