Just curious for anyone who has seen their X go into the withdrawl phase, how long did it last?

I am just having a really really really rough time right now. The short story is I was told by my XH that he doesn't want to speak to me anymore. That he needs to abstain for things that cause him emotional angst, and while he doesn't admit it 100% of the time being around me causes him angst and probably always will.

I am sure I will write more this weekend since my heart just aches.
Thanks!
