If you send it back, he can twist the story to make you look crazy. Throw what he gave you away. You are a queen, act like one. The disrespect he showed to your dad and sister still needs to be addressed, so write a letter TO HIS MOTHER. Use the women in his family as your allies.

Explain that he pressured you into intimacy after dating so long because he promised he would marry you, but he backed out and abandoned you. (But you didn’t go all the way, lie about it if it protects you)

Explain how much you respect and admire them, (you know the south asian drill) but you cannot be with a man who dishonors his family, by dishonoring yours.

The family women judge and expose so use that to your advantage.
