What Serenity is basically saying is, you need to detach from his mood swings.

Did he ever respond to your letting him be free email?

What was his main reason for leaving now?

If he was drinking alot more, when did that start?

Right now the best thing to do is to not contact him. He's already come to expect it and seems to punish you by not contacting you.

Do you think there's another OW?
