Girl, it just depends on the reason of the breakup. Was he unfaithful? Did he beat you? Did he take money from you?
Consider: Did he finish high school? Is he going to college? If not, does he have a job? Love is beautiful, but if this guy is not trustworthy (cheating, stealing, lying...) or if he is not willing to work at a good future (either by studying or by working), BE VERY CAREFUL.
I wasted a good future on a bad guy. I could have had a university degree and the nicer salary that comes with it. I was stupid and in love... for 6 years. I found out he was ceating because he gave me an STD... (Fortunately, I got treated and now I am healty). We broke up. When he asked me to take him back, I told him no. I still loved him but I chose for a better future, even if it meant crying myself to sleep for months.
Guess what? I met someone else and he is wonderful. We live in a nice house with a beautiful garden, I have the most beautiful baby daughter in the world, we have no worries about money and I am SO happy I dumped the creep.
