Title pretty much explains it. We were broken up for a couple months & she told me she had a ONS with some guy at his place. Nbd because I was fucking other girls too

However, she told me nobody has been to her place, and has only been with the dude mentioned above. I don’t believe neither of her claims.

If I decide to pursue it (tired of wasting time on her), how would y’all go about asking her about it without coming across as confrontational?
