Hi aabh
I read every post in this thread. I am very sorry for your situation.
I too was once where you are now. My simple advice is to gather up whatever strength you have left & run for all your worth. I don't say that lightly. Save yourself! He is not going to help you do that.
Meth addiction is extremely destructive. You don't even use this drug but are being dragged down by it. There is no bottom to this rabbit hole. Its very deep dark & never ending twists turns. Its a horrible place to be & yes ive been there.
Please step way back from this situation. The closer you stay with it the harder it will be for you to sort this out in a healthy manner.
I know its very hard. I know exactly how you feel right now. I have been there maybe times 100.
I can tell you that creating distance from this situation & giving yourself time away will help you. Help you to regain stability.
You are contemplating moving out of the country, buying a house, & starting a new business. If any of this has to do with him I would think about it carefully. If not then ok you have a lot of major changes to focus on & keep you very busy. You don't need this huge turmoil & distraction from a meth addict screwing it all up.
Please take care of yourself.
