I would suggest you to stay away from that girl because she has no feeling for you.She just ruined your love and use you as a bank account.Don't waste your money and feeling for such a selfish girl.Forget about returning back the money .I am pretty sure that she will not return a single penny to you dude.

Disgusting behavior by the girl
Why are you worried now just ignore that selfish girl and passed away.
Let her remain busy with someone else.She will get the same as she did with you .
