<human>: Yesterday morning my girlfriend of 2 and a half years, (and good friend for five years) broke up with me. I know if I talked to her we could work it out and get back together, but the past few weeks I've been thinking about what it'd be like to see other people. Now that I'm single that's a scary prospect, and I know seeing my ex with someone else would tear me up inside. I know if I'm going to get back together with my ex it needs to be soon, while the problem can still be sorted out, but I don't know whether I want to be with her or see other people. I feel terribly selfish. Being with her was easy, I knew how to make her happy, I know everything about her. We had talked about spending our lives together, going from that to having nothing planned makes life look really bleak. I'm always being told I have a whole long life ahead of my, and that I need to experience it to the fullest, but I don't know if that means staying with her, or moving on.  I don't know what I should do.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: recent break up, possibility of getting back together, I feel horrible and selfish for wanting her and to see other people.
