<human>: Hello people of reddit. I sit here writing to you all today as a very confused man (24). A dalliance with a crush/friend of mine (F22) this summer did not end well at all. We had sex when she was in the tail end of a relationship; we confessed to having had feelings for one another (I've known her since last winter); she rejected me for her then boyfriend, followed by tinder rebounds, all the while "using" my affection to do favors for her. She's not completely to blame, as I in fact allowed her to treat me this way. It got to the point however that I cut off contact, trying to salvage my own self worth. I didn't hear from her for six weeks. I thought that sad and desperate part of my life was over.

That was until earlier this week. She reached out to me essentially begging for my forgiveness. She claimed that how she treated me was unfair, acknowledging how messed up it all was. Thoughts and sentiments I thought had rightfully and deservedly died are starting to trickle back, and frankly it worries me. Am I still as stupid as ever? I should have learned to stay well away from her, but it would appear the hold she had on me had been simply lying dormant beneath the surface. 

As of the moment, I am unclear about her intentions. Does she want me to be her friend, or has she regretted her decision and rediscovered the "feelings" she once claimed were there? 

In short, what on earth should I do?

Could you distill the essence of the text into 1-3 sentences?
<bot>: A crush who spurned me, and used me, regrets how she treated me. I'm unsure of why she wants me in her life again, but, given the opportunity, should I give her another chance?
