J.:
I'm truly sorry that your marriage is crashing. There is SO much going on - I think I too would be fighting for days. A good fight every once in a while is a good thing - however - DAYS of fighting is NOT a good thing.
okay - after reading your post - more than the fighting what struck me was that you said "he's not affectionate whatsoever" - so please tell me what drew you to him in the first place and why you married him?
YOU BOTH are controlling. YOU BOTH WANT YOUR WAY. Therefore you are fighting.
Make a list of the problems you are having - have him do the same. Then make a statement as to HOW **YOU** would handle the problem and WHY. DO NOT use "you are a jerk" or "this is because of YOU".
If you have problems with HIS BROTHER - your comment needs to be "I feel that Jared (just sticking that name there) is interfering or butting into our marriage.
When you are done with your lists - hand them to each other and read what the other said. Is there a compromise to be had? If so - start there.
If you have already put divorce on the table - it sounds like you are both ready to give up and fight with each other instead of FOR each other. What are your priorities?
Life isn't easy. And marriage is a HARD. I know there are people who make it look easy - but it's not. You get out what you put into it. It's a full time job. I've said before - marriage is like a garden - it needs daily attention to pull the weeds, prune the flowers, mulch the ground. If you SAY you both want to fix your marriage - NEVER mention DIVORCE. You are giving yourselves an escape route instead of dealing with the problems. I guarantee you - even after divorce the problems will still be there.
You both need to learn to "fight fair" that means - no hitting below the belt. No name calling. No screaming - it really doesn't help.
Since you are both willing to seek counseling? Go to your church. Most pastors, priests, rabbi's are all willing to deal with marriage counseling. If you don't go to church, find one. Get your marriage back on track. it's YOUR marriage - not anyone else's. Your mother, father, brother, sister NOR his mother, father, brother or sister should be able to interfere or make comments.
