When do you know you have to work more on your thoughts to create love or walk out of relationship?

I am a place where I don’t feel anything for my boyfriend.
C: I don’t feel in love
T: I should work on my thoughts to feel love
F: I feel guilty because I don’t know how and I’m not sure I even want to. I feel guilty to not totally want to

A: I am acting cold and distant

R: I am drifting apart from him even more

How can I make myself want to love him more? Before I would have left, but since I know about the model, I figured I create my reality so how do I create love? Could we spend the rest of our lives with anybody? Might sound like a stupid question but I’m lost.
