Yes I would expose them, to save people from hurt in the future, either way they’re going to be hurt finding out they’ve been played/cheated on.. but it would all end in tears anyway, i’d rather someone told me than kept quiet. The longer it goes on the longer these women have to fall in love with the said cheat…
If your worried about looking like a bad guy, it’s only name’s on a screen.. they’ll know in the long run you did them all a favour. Just ignore them and know you did the right thing..
Just be careful how you do it, make sure you do actually have solid evidence and it’s not a case of he said she said, I seen this I seen that…
