A.,
I dont think that you are being irational at all!! I am also in the same situation as you. My ex husband keeps the same company...one of them just got a felony DUI! Im a single mother and I have three kids 8 yr old twins and a 13 yr old and as a Mom the hardest thing to feel is that you cant put them in a bubble and protect them...I know its hard :(
You are right on this one in my opinion. The environment is more proper for your son with you and other kids for him to play with. My ex does the same macho thing "my son and father" stuff....but here is the thing....no 8 yr old is going to want to hang with grown men and watch hours of football vs. playing with children his own age. At least I know my two 8 yrs olds wouldnt! :)
Your doing great...no worries you sound like a great Mom :)
