Okay, so you're gf wants you to pay for her vacation? Then she wants you to pay for a louis vuitton purse? Dude, this is not generous what you're doing, it's called being a pushover and letting her step all over you. You don't have to allow someone to step all over you in order to be generous. I say she's using you.
for godsakes speak up !! if she wants one , she should buy it herself..does she really realize these bags cost?,and with the economy the way it is ,she should settle for a knock-off..nothing wrong with that...some of these purses are rediculously priced for something you can get for a fraction of the cost and they both have the same purpose..to carry something...who cares if its not the real thing..bet she doesn't do generic either...don't do it !"
Oh my. It's clear to see that she is just using you for financial gain. Open your eye's and see reality before you. She is definitely without a doubt a "gold digger." "Drop her like a bad habit before you end up in the poor house while she's laughing to the bank." You may be the most naive man I have ever come across but you deserve respect and to be with a woman who loves you for (you) not your bankroll. I wish you the best.
With all the questions you posted regarding this woman, apparently you are not happy, she appears to take advantage of you whenever she can so in my opinion, it's time to walk away. Life is too short to be stuck In a one-sided relationship. Good luck.
