Feeling so sad

So I have a big big discussion with my boyfriend because he dedicate to me a sad very sad song who actually make him remember his ex.

I know that because back in time he told me that.

So when I was there hearing the song I was kinda freak out and then we fight.

:(

Now I am feeling so sad because he said that I hurt him and that we don't have a future if we always fight and I am feel in so sad right now

How I can control my moods to don't get mad so easy?

I mean you think I exaggerate?
