I am sorry that you have such hardship in your marriage, crazy.
Before you make any emotional decision, think rational and talk to your
husband. Suggest counseling together and go from there....
Crazy, you are both very young and you have started a family at a very young
age, this can be overwhelming to anyone and especially young men who
haven't had an opportunity to live the single life for all too long.
For the sake of your kids, you both owe it to them to try to work things
out and go to joint counseling. I sure hope it will work out in your favor,
good luck to you, honey!
