I can't decide if my ex is being very inappropriate with our pre-teen

I need some help deciding if something is inappropriate or not. My heart tells me "yes, very" but I also acknowledge my judgement could be very clouded right now.My ex (m30s) and I (f30s) divorced a couple years ago. I had known he was into wearing womens' clothes, however he kept this very private. After our separation, he became public with it. I have no problem with him doing this, just to be clear. We are not on good terms (to put it lightly unfortunately); this is why I believe my judgement could potentially be off.We have a pre- teen daughter who I have primary custody of and he has her about 25% of the time. She just returned home from a weekend visitation with him today. She told me he had her come into his room and she stood next to him as he went through his panty drawer, sorting through several pairs of panties, looking at sizes. He wanted her to try some on so he could know what size he needed to buy her.When she told me this I just kinda nodded my head and thought that sounded really odd but of course didn't say anything to her about my feelings. She's in bed now and I can't stop thinking about it.Is this weird? Couldn't he had just asked her to look at her panties I send her over in to see what size she is in? Am I overreacting? Underreacting? via /r/Parenting https://ift.tt/3k18DtZ
