Dear Steve and Shirley, my ex-husband and I are both in our 40s and we have three children under age 12. We divorced over two years ago and recently he allowed his girlfriend to move into my old house with him. The kids mentioned it, so I asked my ex to let me meet the woman that my kids are around. He got upset and said it’s none of my business. I said I should know who’s around my children and he said all I need to know is that they’re with him and that's all that matters......................................
