I'd ask yourself. "What is it about me that continues to want to pursue an unfulfilling relationship?

Is it familiar to you to stay in unfulfilling relationships? If yes, then that may be the issue here. What she decides is out of your control. You can only communicate what you want.

Get help for yourself and allow others to be who they are. If you are unhappy and have done all you can to communicate your needs then that is really good feedback for you.

You honor others most by respecting their values and beliefs - even if they don't align with yours. AND that does not mean you have to stay married to them. They have their journey and you have yours.

I learned a long time ago "You can love someone but you don't have to like their behaviors"

It sort of sounds like you are "committed" to "fixing" someone and it's not working? Don't confuse that with love. In order for all relationships to work, two (not one) people have to have the desire to get into alignment. And you need proof that each person is trying to reach similar goals.

hope this helps.
