well first of all, you really need to think about why you got married in the first place.
I have been in a similar situation 20 yrs old and married the first guy that asked me, who was 9 yrs older than me, because I was upset about my high school / college sweetheart.
and about 8-10 months later no longer wanted to be married to him because I knew that I had made a terrible mistake by marrying this man. He was so in love with me but the feeling was mutual.
I just sat down one night and made him listen to what I had to say and all he could say was that I was a child and if we tried it would all work out.
Well he was right I was young but he was wrong about it working out I hated more and more everyday.
I decided to pack my things and moved out. He pursued me for a while but eventually he found someone else closer to his age and that truly loved him.
I finally got my divorce after five years. He fought me every time we would go to court or he would move and I finally had to hire a PI to locate him.
I think he did that to make me feel his pain.
As for me I married my high school / college sweetheart and we have two great kids.
Luckly things worked out for me. I just really think that you need to think about why you married him and if you don't want him any longer, end it now and if your upset over some petty things think it out before you do anything you might regret.
I hope this help and I truly understand what you are going through
