Women many options. What you are saying right there, is that you don't feel adequate to be with her because she has more money thant you, this being an insecure guy.
That happened to you because you didn't felt "worthy" of a woman who happens to have a wealthy family. No wonder you failed.
This is you projecting. Do you feel that low of yourself that because her family is wealthy, you don't think won't do so good?
Iron Rule of Tomassi #8
Always let a woman figure out why she wont ƒvck you, never do it for her.
See, this guy knows what's up.
