Bloody hell, Barry. I have only recently stumbled upon this thread as I'm not such an active member as I once was but, my goodness, you and your kids have been through the mill. I hadn't realised before that your marriage was in such trouble or that your ex-wife was an alcoholic. I don't know how you've managed to get through this without blowing your top at least half a dozen times but credit to you for taking the high road and keeping calm as it makes your position so much stronger. Well done.
I'm glad to see that things are getting easier and, hopefully, the end will soon be in sight but I'm afraid that, like World War One, it won't be over by Christmas but the New Year should see it done.
Looks like you've got great kids and having found a new partner must have been a big help so good luck and keep going.
One thing I need to know. Do you have a punch bag in the garage for those times when you just need to vent? Otherwise, how have you managed it without exploding?
