A, Glad to see that you and the family did go to the fireworks last night.
A, he does think about all of the happy times he spent w/his family and that is one of the reasons he can't be around much when a holiday comes along. It's not that he's tossed the relationship in the can. Guilt/depression are eating him alive and as long as he's got this going on, he can't be around his loved ones during the "family" gathering type of holidays. It reminds him of what he's left behind and what a boob he is.
So, pick yourself up, get in that pool and have a great afternoon. Let the boob work today and earn some extra bucks and then go back to his little room and sit and sulk. You and the kids should enjoy the holiday and thank the dear Lord you are healthy and have each other.
Now, get out there and enjoy the 4th of July!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
