I am sorry that things haven't changed in your situation. I do understand how you feel and it's very frustrating when one half of a couple goes out there and has an affair. Five months isn't all that long for an affair and the euphoria of that affair does not wear off very quickly. It may take her a while to even realize what is going on w/the situation and waking up takes even longer.

If your wife were in a coma or had a life threatening illness that had lingered for five months, would you be as quick in wanting to divorce her? If she should wake up before the divorce is final, would you consider taking her back?

As for the divorce paperwork, she may drag her feet on it because she may not really want it. Dig deeper for patience and I do hope that she comes to realize what she is losing in the way of a spouse, lover, and companion.

Continue working on yourself.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
