Learn from this lesson and try not to repeat it. The best thing to do is to stay single and just go out on dates. They can't break up with you if you're not in a relationship. Date around until you find the right one.
If you love someone, set them free, if he comes back, he`s yours, if he doesn`t, he never was. Sad but true!!! there`s plenty of fish in the sea you will meet someone soon just try to think about what you would like in a relationship, instead of what you don`t have.
