Feel like I'm losing my family...

Advice appreciated. My fiancé was diagnosed a few months ago with BP. He's always struggled with the ups & downs, but when he was let go from his job in April, he "snapped". His episodes have gotten increasingly worse, he's become extremely self centered, deceitful, & manipulative. It took months to get his unemployment approved so Naturally were having money troubles, rents behind, as are other bills, his truck was repossessed (not in my name thankfully) & when he wants to be frivolous and I refuse, he just goes and asks his mother. Who has always given into his every whim. He has managed to talk his parents into getting him a car, claiming he would make the payment and tell me that his parents would be. I confront him , and he calls me controlling. When I told his mother about the deceit, BEFORE the car was purchased, she just shrugged it off.

He's been abusing his meds, lying to his doctors, even asking for meds. Every injury is excruciating pain, and I can't tell you how many dr, ER, & urgent care visits there have been in the past 2 weeks. I try to go to all visits in an attempt to keep things straight & ensure everyone knows the complete med list. I even began giving him his meds so he doesn't abuse them. He talks his little brother into buying him things also. His concern for everyone, including me.

I believe he his spiraling out of control & don't know what to do. I've called & can't have him commuted for the BP or substance abuse. I can't talk to him , & I can no longer confide in his mother as she is only enabling the behavior.

I don't know what to do. He won't acknowledge his behavior and claims I am the problem. Sure I occasionally lose my temper but I am learning to deal with the BP, but I feel there is another issue beyond the BP.

Thanks for the reply.... I didnt send him to his parents, he ran away. This is the first time he has done that. Im struggling with when to walk away... I know there's more going on than the BP, and we havent gotten he right combo of meds for that just yet. Im struggling with knowing that he has to want to help himself, and understand that bc of the illness he cant control all his actions and reactions.

Im trying to give him time to cool off and will be talking to him when he does. Im sure he;ll feel attacked, but I know that I have to call him on his lies, and let him know I wont stand for it, or the abusive behaviors any longer. Hes either going to have to make an effort to get under control or unfortunately I think Im going to have to walk away. It just hard to give up on the one you love.
