Tad you still have a ways to go. My ex remarried and had a baby and with each step I told myself i was taking it just like that...."step by step". of course mine remarried and got preg. 5 mths after we divorced but the hurt is still the same. It took me 3 yrs. or over to actually be able to hear things about him or them and it not make me nervous. I hardly think of him now. If my son didnt live with him (again), I prb wouldnt think of him as much.
It will be alright Tad, the worst is behind you. You will have setbacks but it will be OK!
Try to stay busy as much as you can. Your life is NOT over. There is so much more to life than marriage. I loved being married but there is so much more than that. Do things that make YOU happy. You have your kids, that is something GREAT! There are always others whose situation is worse. Be thankful Tad!
