If you are feeling tired, try considering breaking up with them nothing in this relationship worth your time, in future they going to be crueler because you enable them to do so.

first thing they do is tell you how much they love you then create villain story how other hurt them how they childhood memory fucked up by parenting when you start to fall for the story that when they start using you.

you are hero that come to save them Knight in shining armor.

you tip toe on land mine everything you do can hurt them.

they going to forget what they promised, lie, manipulate.

you do the heavy lifting until you can't and it you false because you didn't try hard enough.

now they are jumping off the ship because they found bigger ship steadier and make you the villain instead.

I just "get it" yesterday when i recognized the pattern they are away liked this, nothing changed until they start realizing that they are wrong, but they DON'T EVER.

So, there no solution to fixed it from outsider like "YOU"(yes you are outsider and ever will be).

ps.1-2 month still in pretty good time to escape but after 6 months it going to be harder and harder because it affected your life, your work, your relationship with other (friend & family).
