Each time you get together and it is a positive experience you will leave him with more things to think about.
You have to learn how to be friends again, and this is a good starting point.
Try to remember, IF your Husband is in MLC you will have years of BS to tend with.
If this is just a case of a Husband who is a bit disillusioned in his Marriage and his life and wanted to test the waters.....then give him something to come home to.
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.
