Emlouhara, you've done the right thing ending this relationship.
Be kind to yourself.
It sounds like the split was for the best... You bring out the worst in one another. At 23, there is no reason to waste your time on a guy who can't (for whatever reason) get his disorder under control. Aside from that, he may be a full-blown alcoholic. And any way you slice it, you couldn't be harmonious one another. Harmony in a relationship is crucial.
