I suppose this is where friendship rubber meets the road. For both of you. Do not be so nonchalant. You care and you do not, but caring makes you vulnerable to getting sucked back in. Wolves cut it off. They know when to break ties and move on. You are not a wolf. Tho you are glad to be away.
But.
Know your boundaries before you go back in
Corri,
I think this post highlights what I've been trying to tell you about yourself. The wolf/lioness is not the only animal who can be strong and enforce boundaries. If the lioness is weak the whole zoo will be out of balance but the bunny, monkey and cow shouldn't have to call on the lioness for assistance. The zoo keeper should work to ensure this. For instance, the bunny is the animal that wants physical affection. Let's say I hook-up with a guy and after sex I roll in for a cuddle and the guy signals "no-cuddle". Strong bunny is the animal who should deal with that situation, not strong lioness. You can pretty readily see how I would be psycho-girl if I did call out the lioness to deal with that and how I would be a different kind of psycho-girl if I dealt with it in weak bunny mode. I actually think your strong monkey is the animal who should be dealing with your XBF's AFF usage, not strong bunny or lioness, however I shall be cryptic and let you figure out why that would be the case.
