B “if u need to- tell him your seeing someone else (i believe it is permitted to lie i can get you sources in halachah…)”
Why so he convince her to cheat on her bf/fiance/husband?
Unless frum guys have mastered their YH completely, a bochur can spin a girl’s “I’m seeing someone else” to hear “I like you but I am burdened by my current SO and if only I wasn’t with him because I am so into you…”
