As far as the children are concerned they are the most important people to consider durng the MLC stuff.
As parents sometimes we have to suck it up for the sake of their well being and at other times we have to enforce strict boundaries to protect them.
Perhaps setting up a regular time with your H to call the kids would be best. I tried to get my H to call the kids after school so he could ask them about their day, etc. You kids will also learn to look forward to this special time with him.
In my situation there was a huge time difference so it didn't work too well but in theory.....
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.
