Most Helpful Guy
The only thing you can do is step up and ask him if he wants you back. (You didn't say who broke up with whom and we also don't know the "stupid reasons" YOU may consider them stupid but they mean something to him)
So I am just generalizing due to lack of any information on the break up that if you broke up with him... dont go back and get rid of those feelings...
if he broke up with you... its still the same thing but there's a chance at least.
