Why divorce, just try to remember the good things, everything cannot be all clean and tidy, sometime you will face rough bump to go over other tim eit will be a mountain of shits that will seem unsurmountable(is this a word lol), In the end you marriage will only be more solid imo. I went trought rough time with my GF we had one kid back then, we found away to put aside our problem for our first girl (this was the first step) and after that we repaired our relationship (we fixed it with ducktape at first and then fixed it for good).
Seriously it cant be said enough COMMUNICATION is the best tool you have in those kind of situation. Many people around the 2-3 and 5-6 year mark just feel their relationship tend to be blend and without sense NORMAL you got into a routine and it is normal that things seems ''boring'' sometimes, JUST SPICE IT UP, When you married on the contract you signed it wasnt only written for the better ....but also for the WORSE, if it is in the ocntract it mean its gonna happen someday sometime lol.
OT: Why do you want to leave, what it your maiin reason for leaving ? (dotn tell me that you cant get along anymore this is easily fixed by talkign to each other)
