Have your deals off phone calls and chats so he/she doesn't have a leverage to blackmail you.
Go ahead with the deal, extra 10k wouldn't be bad, also people fall in love mysteriously.
You guys might end up falling in love and having beautiful kids.
Invest the more in altcoins and become millionaire.
Life is risky, success is a factor of calculated risk.

My pence, hope you like it.
