"But in answer to your questions, I am scared for him if I leave. I don't know what he would do."
Thing is, is HE scared for himself if you leave? He bloody well ought to be.
Does HE know what he would do if he carries on like this, and pisses you off enough to doe the absolutely right thing of telling him to sort his own life out. Again, he needs to be ready, cos he seems awfully close to finding out.
OK so he has a back condition. I have a friend with similar, she can manage working part time only. It renders her in agony, she has been in pain since she was 14. Staying off work is more detrimental to her health.
Your H is not contributing anything to this relationship or the family at large.
You are supporting him and running about trying to make ends meet, child care etc and he just sits there and lies about money, runs up debt and gets you into more trouble, without any way of actually putting this right himself.
Buying drugs, lying about them and feeding you a pack of shite about the Dr telling you to support him more. I'll bet DOUBLE what this manchild has run up that he never even mentioned it to the Doc.
He is a proven liar, with reason to manipulate and twist things so he looks better. He has no right to this status he has carved himself.
He ought to be worshipping the ground you walk on for what you are putting up with.
You are carrying the family, and he is making it harder, not better. Until he is actually contributing, even emotionally for example to be a brilliant House Husband for example, then he needs to STFU.
Remind him that whatever he wishes to use as an excuse for rage, for not doing anything to help, or for actually running the family further off the road, it is never, ever acceptable for him to call you names or rant at you.
Tell him the next time he opens his mouth in that vein then he better get his coat and hat, cos you will be packing his bags.
Seriously, he is making excuses to be a twunt. If you can't actually contribute in financial terms, you do so in others. You do NOT make matters worse by lying and running up debt.
My dear friend treats people with respect and honour and holds down work and stuff. her back was broken, she is in constant agony, has had countless ops, all unsuccessful. She manages to be a nice and wonderful friend.
