I don't know what stage your wife is in BUT the very fact that she is open to dating you is a good thing.

For all you know she is just telling you she wants to date other people so as not to commit to you right now. This doesn't mean that she really will date anyone else.

AND...

The fact that she is being honest about her feelings is something you need to give her credit for as much as it may hurt.

There can be no testimony without a test.
I am praying to go through this test and come out the other end with a new and better marriage then before.
