I abused and forced my s***** desires to a girl.

We never had a real relationship. It was only a summer fling but I know we had the potentials to stay longer. If only we weren’t going to live more than three hours of flight apart for the next 6 months I would have made a move. She was a cute, kind of innocent girl, a kind I haven’t hooked up or had connection with in quite a long time – since I was busy traveling here and there, meeting people who are also open for one-time hookups; fun, wild parties, ambitious ladies in career wanting to have some fun in a city she only visit for business, this kind of stuff. But damn she was different.
That one last night we were together she somehow refused my advances, telling me “I’m too tired I got a train early morning.” Of course I was disappointed.
Not long after she sleep I started f******** her, she moaned and enjoyed it although keep refusing when I tried to put the d*** in. I couldn’t help but to continue until I came and got tired. Morning after we had a good quick goodbye makeout session as we both have different trains to catch. she never said anything until a week later she called me, and mentioned the R*** word, accusing me of it.
We had a fight.
For a good part of two months after that we didn’t really speak to each other. This Thanksgiving I was doing a roadtrip down east coast, including NYC where she works now (just an intern, she just graduated this summer too). I felt after some time I needed to clear all this mess so I asked her out for a coffee. She said “I can’t do today, got work until late. Tomorrow…? But I’m also still not comfortable, I don’t know tbh…”
But that was the last day I was in New York.
Not long ago she stopped replying to my text for no reason.

I still feel guilty that I violated such an innocent girl, and that I might never have another chance to say sorry in person
(She’s leaving NY next March)
