I've been married for 8 years and I know how hard things can get sometimes, and.. having in mind that my hubby has ADD, ohh well, I'm gonna leave it to you on that...LOL
I think you can get thru if you guys have a good and open comunication. she needs to understand what might be trigering you and when you feel that you are gonna explode, take a walk, and try to keep you mouth shut.
hang in there hon, you are not alone~
