Of course! And if you start to feel uncomfortable venting publicly, we can always do an aggie if you want to

I don't blame you, As of right now you're going through a tough time and wanting to reform bonds so that you don't feel alone isn't something you should be angry at yourself for. You're simply wishing for comfort again. Your ex leaving you and your friends without warning or anything like that is wrong though. They should've at least let you or your friends know how they felt instead of just abandoning you. It isn't your fault they were so terrible to you and them making you feel as if it is, is not at all right whatsoever.

I hope they know that leaving without saying anything is much more worse than saying something before you simply abandon someone, especially someone you were extremely close to. Perhaps they didn't know how to approach you about it, but still, they should've tried to give some sort of sign at least.

Either way, You shouldn't have to be pulled down by what they're doing, even though it hurts. You're allowed to take all the time you need to start to recover, it isn't something you have to do or force yourself to do for the sake of others. Its still your life and your mind and you should be able to take things one step of a time. It doesn't matter if people walk faster than you, you're still the fastest person you know. All you're doing is taking things at your own pace, as you deserve to.
