If you have been trying to GAL for 6 months now and you still have not and are still struggling to GAL then it's time to find a new approach RIGHT NOW. Yes, we get it, you have lots on your plate, we all do. You sound like an amazing mother. You sound like a hurt wife. You also sound like you are lost because you don't have control (which I suspect is an issue for you). Stop thinking and start doing. Stop using fancy words and in depth explanations and do something right this minute for YOU and YOU only.
With all due respect do you think your husband would find you remotely attractive if he came home to find you watching DVD's and "licking your wounds"? NO!
Start setting boundaries because right now you are making it *very* easy for your H. Let him crash and burn.
You should be telling him that NOTHING else will be removed from the home you share that is joint property. Not one thing.
You should tell him you will need xxxxxx dollars per month to run the household and other than that shove all the business debt he created back on him to take care of. Give him a good taste of being a single parent, being loaded in debt he created with no emotional support to deal with it. Let him see the solid, stable lady in his life is gone. Then maybe the hottie and karate won't be quite so interesting to him because after a roll in the hay, well, young hotties don't care much to tend to children and bills and debt that doesn't even belong to them. That is boring!
Look - I know this is hard. I kid you not I had a nervous breakdown from the stress. You write fancy but its all excuses and justifications. STOP. You are only hurting yourself.
Now, you can think I am an uber bitch and that is just fine by me. I am sure somebody will find a more "kid glove" way to say this but you really are only hurting yourself more.
Very wise advise. ( I have a hard time taking of the kid gloves.)
