<human>: Alrighty so I just got out of a 3yr relationship and for my thought it was awesome but apparently not to the other half (18/f). I had my time to think and we ended on a good note, she is going to school, I'm gonna work. What I didn't expect was how much of a lost guy I would be, I feel super alone and my mind is playing crap on my heart. I have a bit of a thing for a friend 20/f who is dating one of my old highschool buds. I don't talk to him anymore but I talk to her a lot and we have had some.. Interesting talks but that's all. Now I wouldn't mind more but out of respect of him I wouldn't do anything, but this loneliness sucks and she admitted that if she wasn't with him she would like to be around/with me and see what would happen. I just want advice for a lonely guy that doesn't party, meet new people or go out much. Help settle my thoughts.

Can you condense the text into a few key points?
<bot>: broke with 18/f of 3 years, 20/f has come to my interest but I don't want to approach even though she has given my fragile likeness a push.
