Has anyone ever gotten married young? have you regretted it?

I'm 21 and married. I knew my husband for a whole 3 1/2 months before we decided to get married. He seemed like the perfect man, but once I married him I got to see a side of him that I don't think I can live with. He is in the army so we had to rush our marriage. I really love him but I don't think I can forgive him for certain things he did. I'm just looking for some kind of advice. I had to leave all my friend behind when I moved in with him and I don't really have anyone out here. Please help 😩
