Sugar, may I suggest that you take just one step back... a lil time off... If she's coming out of a relationship, I mean, it sounds like she's VERY confused and doesn't really know what she's doing. And you, you sound like you don't know how you really feel, do you? I mean, if it's just a crush, physical thing, or if it could evolve into something bigger...
So maybe if you just take one step at a time, take things slowly and try not to get messed up by the mixed signals she's sending to you, it would make you a lil less anxious. Anxious is bad. And she's not helping, so... protect yourself a little, you know?
Doesn't mean that you gotta deprive yourself from pleasure or anything, but you don't need to be all exposed, u know what I'm sayin'?
