That is crazy of him to compare you to other girls.
He is just trying to guilt you into it by mentioning someone else. Don't worry about that tho. It is probably all in his dreams and he couldn't get anyone to do it. How long have you been seeing this Romeo? Is this the first time he has asked for money? You have to be careful because con men are really talented and they know who to pick.
This is nothing against you, but maybe you should make a list of pros and cons. You haven't him given any money yet have you? My bet would be that once he had the money he would be out of there. You are a smart woman. What do you think you should do? What your mind says and what your heart feels are 2 different things. Know your worth girl.
I know what I have given you. I do not know what you have received. ~Antonio Porchia
