I (F, 45) own two properties aside from my primary residence and share 50/50 custody of two children (7, 11) with my ex husband (M, 45). Of the two additional properties, one I rent out and the other I occupy during my non-custodial time and will never rent it or have my children there as it contains “equipment” for my leisure. Last week, I had a friend’s birthday party (7 women) at my leisure home with male entertainment(4). One of the female guests (a mutual friend to my ex and I) told her husband details of the party. He then told my ex-husband. My ex contacted me about the party, but only inquired of the equipment I keep in the home. My response was, “respectfully, we’ve always kept communications about the kids, let’s continue to do so.” His response was he’s concerned about the kids being in that house and wants to see it. My children know nothing about this home and until this party, my ex and I had a pleasant and cordial co-parenting partnership. I don’t want to invite him into the home; as one of the reasons I divorced him was my high libido and having a dead bedroom. Understandably, this hurt him and seeing how I enjoy being pleasured could affect how we interact; however, I want to reassure him our children’s safety is paramount. How should I proceed with this?
