Three words- Everlast chastity belt. LOL!
On the serious note, I know that I got hung up waiting for something BIG to happen in order to justify making my move, and from what I've read around here that seems like a common theme. Waiting for "the big one", or for things to be "bad enough" to justify action. But by the time things escalate to that level, it almost blends into the landscape of badness in the relationship.
I know I've had a hard time ending bad relationships in my life. It's a skill I want to develop before I "get back out there" as they say. Until then it's the Everlast chastity belt for me.
Take care. You'll do what you need to do when it's the right time for you.
