<human>: Can you provide a brief overview of the text?

Throwaway because my ex frequents Reddit.

My ex is 26 and I'm 25. we were together for almost 3 years with lots of breakups. AND I MEAN LOTS. The breakups never lasted long so they were more like little fights when we just didnt talk. But it's safe to say we had a lot of problems. For the past 8 months he and i havent officially been boyfriend girlfriend. We still hungout, talked every day, had sex, were exclusive, etc. Just didnt have the label. there had been lots of breakups in this past 8 months. lots of "THIS IS ACTUALLY IT" and then we'd get back together. We are so weak for each other. I just can't imagine being with anyone else. He's the one I wanted. 

This last time we were together and going strong for about 3 weeks. I really wanted to work on our issues and fix things. Yesterday he changed his mind again and said he doesn't want to work on this anymore. I told him this is really the last fucking time and that i wont be taking him back again. 

I need advice on how to stay strong. Im scared that if he asks for me back im gonna just let it happen again because i miss him. Then he's just gonna hurt me again. How do i stay strong and not let him back in?
<bot>: My ex dumped me and i want it to be the last time. How do i stay strong if he asks for me back?
