Please help me...really needing some advice with this one. My ex partner is letting his girlfriend sleep beside him & our 4 year old son. I think this is so inappropriate, totally disrespectful. My son always had sleeping issues & ended up beside me & after split & moving to New house he sleeps better beside me. Last week, my son said in front of his dad & me that he slept beside them. Have told my ex my opinion but he's blaming me, saying all my fault, because I've let my son sleep beside me. My ex only sees his son one day/overnight on a Saturday. Today, I've decided he shouldn't sleepover & made an excuse. What do I do? What should happen next weekend? Am I being unreasonable?
