<human>: Me, my GF, and her best friend celebrated my GF's 21st birthday last year around this time. We all got very drunk, and my GF passed out, and we dragged her up the stairs. We made it to 3rd base, but I was very whiskey dick, otherwise we would have done the deed.

The day after her friend and I talked about went on, and nothing has happened since then.

Recently, I've been thinking about that night a lot, and thinking about my GF's friend, sexually, and emotionally. 

I really do love my GF, but she's talking about moving in with me, but she barely has enough money to support herself as is, and I have this terrifying feeling that I'm going to become a permanent crutch for her, and it makes me feel very apprehensive about our relationship.

My GF and I get along very well emotionally, and sexually, and generally we communicate very well, but I haven't been able to tell her what happened, and how I feel currently.

Last night I decided to send a lengthy message to her friend about how I felt, and how I wish he had told my GF, since I felt I had to get that off my chest. I haven't heard from her yet, but I guess I'll see what happens.

I'm just wondering if I'm insane or not. I feel like what I did was very perverted, and I'm not sure what I want to do with my future in terms of relationships.

Can you give me the gist of the text in a nutshell?
