How to prepare myself?

I know things are not okay with my bf, from his side, I know he’s not that serious abt me, he doesn’t seem like he cares.. at the same time he wants to be with me.. but I know he’s manipulative and a player and he lies a lot..

My question is how to start to prepare myself mentally to break this toxic circle?

I love him or maybe I love the idea to be with someone but in some way I feel am

Attached.

I wanna start moving on, while am with him.. how to start to distract myself? I want to prepare myself.. please help me??

First I want to start to care less…
