Hey Cordelia,
As long as they can manipulate you into coming back they will. You have to set your boundaries and stick to them, but you also have to be ready to accept what may come along with that.
For me it was a no brainer. If they couldn't accept me for me then I didn't want to be bothered. I don't have the time or energy to be manipulated by religious fanatics, I chose the door.
Good luck to you but remember as long as you give them hope that you will one day be apart of their organization they will continue to pressure you.
