<human>: A week ago I broke up with my gf of 4 years. It was a hard decision to make but I realized I wasn't happy in the past couple of months and it wasn't going to change. I find myself thinking about her a lot and I remember most of the good times that we've had. Thinking this I want to go back to her immediately but I then remember the reasons why I broke up with her. I feel like I'll be happy again if I go back but then we could run into the same issues again. I don't want her to be with someone else yet I don't have control over that. I feel we were really close to each other and would be good friends but it would kill us to see each other with someone else. I'm not ready to go back to her yet but I want to really bad. Do I just need to be single for awhile? Should I try to find new companionship? Should I go back to her and hope things work out for once?

Can you condense the text into three sentences or less?
<bot>: I shouldn't but want to go back. Could I be happy with her or happier with someone else? Should I wait?
