I hate to sound like a broken record, and I'm listening to you guys for sure. Not trying to be the "but it's different" guy, but... Well, I think I might've not given you a good read on this situation.
First: she didn't say she needs a break. We were talking and she mentioned that it's weird that I've got a bunch of experience and she doesn't. It wasn't the primary subject of discussion; it was an aside.
Second: this girl is all over me. She has through-the-roof interest -- more than anyone else I've been with. Maybe that's why I embrace this idea, it'd be kinda cool to be on my toes again for a little while. I've dealt with the waning-interest types before. Once I stuck it out, second time I knew when to say "**** this" and moved on to the next.
If anything I view this as an interesting opportunity for myself... She's never brought it up again and she doesn't view it seriously. I'm curious about trying it as an experiment. There's high interest and I really don't see this ending in a loss for either of us. She finds someone better? Fine. There's plenty of girls, I'm at a fairly large college in a fairly large city.
Again, if this happens it's going to be _me_ bringing it up, not her. And I do believe it would be a benefit for me if anyone. I do certainly understand the point that has been made here again and again by some of you -- why even bother? Maybe it's better to just break it off with her all-together if I'm seriously entertaining this idea.
