The first red flag is living with someone after two months.

Talaniman rule #1- if single never let a person move in with you until you know them very well (1 year should do it!)

Having said that, it doesn't matter how much you make, she would rather spend your money than have fun, and that my friend is all you need to know to :

Have a straight up talk about this relationship, and what you expect, and know what she expects.

Have an understanding about finances

Get rid of her, no matter how good she looks, or how great she is in bed.

Chances are she is after the money, but if you don't spend enough on her she will leave any way.

Just me, she would be mad buying her own McDonalds, and why are you with a female who gets in your pocket after 2 months???
