Okay, I've tried this multiple times but the rules have prevented me from being able to post it and get the advice I'm needing.  Anyway, here it goes.

In February I [22] began dating a girl [21] I've known for about two years.  We have been friends since we both worked at the same place in college, I would have tried more earlier but she was in a relationship with someone else which ended 3 months prior to us getting together.  I already know that this relationship is the most significant I've ever had and am enjoying it.

The main problem we have in the relationship is my paranoia, I'm absolutely terrified that I'm going to do something stupid and ruin what we have or that she just isn't happy in the relationship.  I knew that most of these fears were normal and that I needed to get over them, but very recently she has informed me that she was only getting a "strong friends" vibe out of our relationship.  Has anyone had this happen or have any advice on what I can do to help push us along?
