You have been such a wonderful help to me and i hope I can return the favor. You have been doing such a great job but you are right you must concentrate on yourself. Let H see the best in you and I agree with the idea of a 180 with MIL. If they both see the good changes in you it will only make things easier.
In my situation with H and so called friends when i ask about them and really listen to him and validate how he is feeling things go wonderfully. It is hard to trust again but you must start somewhere and I have started by believing him when he says they are just friends.
I also have in law problems but you know if you kill them with kindness it shows everyone that you are trying to change and the more possitive times that come from that make everything with H easier. I have decided to not fight with H any more but fight for him and do whatever it takes. And each day it does get a little easier.
I wish you the best of luck and know that you will win this battle because you are strong enough to do what it takes. PMA PMA PMA always even when you don't feel like it.
