I'm 55 years old, I'm a late life dad and a alcoholic. The years ( five to seven) that I was sober on and off seemed not to effect my wife's happiness. The last time I dove off the the wagon she told me that she wanted a divorce. I'm not saying you drink but it is a sad thing when someone falls out of love with you, (you can fall out of love as quick as you fall in love) You have to think of your kid's first and I know the pain the when your partentar in life can look at you with no expression of love. Hang in there it will get BETTER, I'll guarrentee it.
