No one can ever say that a fellow hunter won't have enough support to hold them up when they are down. Its the common thread that ties us together. Keep the faith, stay strong and keep moving.
Sorry to hear - but sounds like you got strong shoulders and will move on and do better things for yourself and your children.
Been there and it sucks...I pretty much hit rock bottom when I was going through my divorce. It caused me to take a good hard look at myself to evaluate whether I liked who I had become or not (I didn't). I found myself taking the blame for the whole situation but thanks to an outstanding counselor, she made me realize that the reality was closer to 50/50. It will take a while for you to figure out who you are as a person and a single dad...give it time. Reassure your kids that you love them and are there for them...keep them out of any drama and don't use them as weapons against your Ex. You'll get through this...if you don't have someone you feel close enough to vent to, vent here...it can be a long and frustrating road to get used to a "new normal", but you will get there.
