Oh, yeah baby
I used to get all militant too. Only I wasn't smart enough to keep my mouth shut. I would just SAY things like, "I've been through the wringer and I have no intention of doing it again. Ever." Or "If you're not sure you want to be around me, do me a favor: Don't. Waste. My. Time." I LIKED being single, loved my life, and somebody would have to be really something special - I mean, add a lot of benefit to it - to convince me I should change that.
My short term relationships were very short term
But then there was that last one, who smiled, shrugged, and said, "I don't plan on screwing you over any time soon. And if I do, you have my permission to kick my a$$ from here to the next county."
I'll be darned if that one isn't still around.
Be as tough as you need to be, good_luck. You've been through a lot and you need to do whatever you're doing in order to flex those self-protection muscles. Be open to wherever your heart takes you....this life thing is a pretty wild ride.
