I think we all become yes men in our M. We think that is what will make our W happy and in return make us happy. When in fact if we would just stay who we are and continue to make ourselves happy and not let all the distractions of kids, work and the house get in the way most of us would not be here right now.
Hindsight is 20/20 but I am glad that you are happier now A and that this has made you a better father and person. You sound really good and content with your decision. But remember your boys are still hurting on the inside and will for quite a while so make sure you are always there for them.
I know I sound like a broken record but my dad called every week and saw us as oftern as he could. He made sure when we were with him that we had fun wether it was throwing a ball around or working in the yard together. He lived 1-1/2 hours away so he missed almost all of our sporting events but when we did get together we had his undivided attention and that is what I remember the most.
