<human>: I have best friend who happens to be a girl. We were really close but never actually did anything sexual or even talked about being together. One point of college life we kind of got distant, I ended up with my now girlfriend and she ended up with some other guy. Eventually we started to hang out again.

2years later (present day) she texts me about being upset because her Boyfriend Ditched her for video games at a friends house. He was suppose to take her out but didn't. Well my S.O. went home for a while because we had a pretty heated argument (we didn't break up or anything [at least I don't think we did]). Because of this she was comparing our situation and asked me if we could hang out. I agree and go to a small restaurant with her.

A little time past as were talking and she asks me if I could buy some alcohol for her (since she was still underage). So I went and bought some and brought it back to her place. She asked if I wanted to drink with her and I though, "Why not."

A few bottles later she snuggling up with me as we watch T.V. (I should of thought of this as a red flag). A short period after she starts feeling on me and I ask her, "Are you really that mad at your BF?" She answers, "What BF? We're done." She showed me the text she sent him about them breaking up and ask if my girlfriend was still giving me the silent treatment. I answered and told her about how its been a week since we talked. Next thing I know she's rubbing my dick.

So as shes doing this she tells me, "Lets forget those two." I was frozen and all those feelings we never acted on came back. It was the toughest choice I ever had to face but I denied and left.

Now I'm here typing and know I'm going to have to tell my girlfriend I just don't know how or what to say without getting her more upset (if she does talk to me).

Give me the gist of the text in a nutshell
<bot>: Had a really good friend, hung out with her, she made a move, I turned her down, not sure how to tell GF without getting her upset more from previous unrelated argument.
