Yup. Stop it all. Sorry to hear you're in limbo and it's been draining on you. You had her on the ropes and it was good, but seems like that wedding gifts meeting kinda derailed stuff.
I would just say - I can't do this anymore and go dark, NC, and get your GAL back.
Everything that needs to be said has been said by you multiple times. You know you want companionship. Go get it man! Don't let her drag you down.
