My relationship will break down soon

Things haven't been good for the last year. She's wanted all I couldn't do for her and it just stresses me out.
I need to find other women in my life and I struggled so much.
Where shall i start?
I've confessed bad things I've done in the past to try and break up with her and I told an old friend about bdsm.
What shall I do?
I've plotted my birthday to be my breakup day.
