:reassuring man hug:
I will refrain from all thing cliche and found on wal-mart posters.
I have never been married and have certainly not aided in the production of vagina fruit, but I can somewhat relate to your stress and anguish.
1yr, 7 months, and 17 days ago my, now ex, girlfriend broke up with me. We were together for almost 4 years. It was a very dramatic experience for me as I had gone into debt, loss my job, and was packing myself up to move to Texas to be with her - forsaking all of my family and friends.
The first thing that went through my mind when she called off the relationship was "why?" Why this? why now? Then I asked myself if it was me. Had I changed? Had I become someone... something that she could no longer love? What could I have possibly done to cause all this?
I was crushed and the world became a black void with little meaning. I got into heavy drinking, binge eating, and I swear my pillows were never dry due to the tears I shed. After a failed attempt at suicide (thank God for good friends) I realized that it wasn't the end of the world.
After that barrage against myself... and receiving very little in answer from her I asked how long has she been feeling this way about me and if it was a result of her finding someone else?
...Hadn't planned on typing all of that.
Anyway dude, try to find out what the cause of this is, how long it has been going on, and if counseling is a viable option. If anything... and most likely as a last resort ask her to think of the children. I am almost sure that this is something that can be worked out... unless you have done something royally severe, in which case you should have seen this coming.However you seem like a decent guy and the fact that you are this hurt about it shows me that the prior isn't the case.
Talking it out with her (sober) is your best coarse of action.
