Wrong to break up

My boyfriend and I were together for 3 years before I moved to another city. Our relationship was amazing before I left. Our long distance relationship lasted for about 4 months before I broke up with him for stupid reasons. He was devastated but agreed. It has now been nearly 5 months since we broke up and I am now living in the same city as him again. Although I have been dating other people since, to try and get over him (my ex has not dated anyone) I cannot stop thinking about him and regret breaking up with him.

If you are writing this, it is clear that you haven't found someone new, and that you still have really strong feeling for this guy. If you view the reason for breaking up as "stupid", then why shouldn't you two still be together? If you still love him and he still cares about you, give it another go. However, if you broke up with him because you just weren't that serious about him, or you wanted to try new things, different people. It could be the case, that you are just bored and lonely now. Being in the same city gives you time to reflect and miss old times, and old feelings. If you think this guys isn't the one for you, don't use him, and put him through another devastating break up.

Well it depends what those stupid reasons for breaking up were. Just let him be, he's probably better off with someone else.
