Fuckity Fuck.
I have been in an on and off relationship - way more on then off but we both had things to deal with and have taken two breaks. He has kids from a previous relationship (his partner died), has been working frontline, we've been living apart.
However, I've just found he's into crossdressing. And has been using the time we've not been living together during COVID to get more into it. It's mainly rubber or latex tight dresses and heels.
About five years ago (one of the breaks) I found tinder on his phone with men matching on (not women). It took ages for us to get over it and he assured me it was just a stress / curiosity thing.
I don't know what to do. I need to walk away right?
