I bought my ex out of our family home a couple of years ago. However he still comes into the house when collecting the children or returning home. Sometimes he will ask to make himself a drink to take on his journey with him. Sometimes he doesn’t ask just makes it. Other times he uses the toilet etc. We have been on holiday and he has been phoning the children on their own phones. When we are at home he calls our home phone. So I’m realising I need to put more boundaries in place. How to do this without upsetting him? How do you and your exes manage with children in the house.
