I need help in the biggest way. I feel so helpless

[TimeHeals]

I want to be strong again. I hate this person I see before him.

You are probably not giving yourself enough credit here. You are strong, and you will get stronger.

He is definitely stuck. To me, he just feels like this is his answer to everything. Getting rid of me will give him the happiness he is looking for; clarity.

That's his problem, not yours. You have to let him solve his own problems because only he can do it, and he can only do it if he wants to do it. All the "you wanting to help him do it" in the world is not going to make it happen.

Let go of your expectations.
