Ch 13 prior to any sex, he gives her an ultimatum to put up with his guiding or end it. Then he says "then let me stop here" and as he's hanging up on her she asks "are you really breaking up with me?" She doesn't seem to accept that it's the end but given that ml then acknowledges that he's falling in love is enough closure

Guys I'm the only one not liking ml for not ending things properly with his girlfriend cause this is literally cheating
I know you guys will say that she is doing the same or worse but ml doesn't know
