I usually try to stay away from giving "relationship advice" but I felt the need to weigh in here. Seems we are around the same age or so and you are in a similar situation as I was a couple years ago. By that I mean young, in school and in a shaky marriage.

My ex-wife and I divorced for a number of reasons, but the reason we divorced at the time we did rather than later was to "save our relationship." The love was still there, but we were unhappy. Don't get me wrong, I'm not saying it was the same. We had 2 small children and felt we had better just call it quits so we don't end up hating each other and making the children suffer because Mommy & Daddy can't stand each other. We wanted to maintain that closeness we had as friends before we were married.

The thought process seams logical enough and perhaps the intentions were good but it was a BAD decision. We gave up because it was the immediate solution to our problem. We talk alot now and it is clear that the love is still very much there but our relationship will never be the same. It changed instantly the moment we signed the divorce papers. It's like inside neither one of you can forgive the other (or yourselves) for giving up. We gave it a short go again after the divorce and it was just completely different (in a very bad way).

Now, I'm not saying that you guys belong together. You may very well be 2 very different people than you were when you married. That's the problem with marrying young, when you both "grow up" it is very possible to grow apart.

What I'm saying is, this is the biggest decision you have ever had to make, and maybe the biggest one you ever will. Be sure and give it all the attention you can before you make it. Maybe even try marriage counseling or something.

Anyway, sorry for the longgg post and best of luck to you brother.
