I have an ex that used to treat me like a king too. She'd buy me all kinds of stuff and take me on trips and all like that. It honestly got old real fast. Personally, I started feeling like she was trying to buy my affection. She also said she was "cool" with me crossdressing, but how she acted showed different. I didn't feel comfortable about being ME.
For you, that's something that you're going to have to be introspective about and I don't think it's something that we as a group can really advise you on what to do. Just a couple of things for you to think about:
1) Are you in love with HER or the IDEA of being in love?
2) Are your top reasons really involving the money and gifts?
3) If she's going to embarrass you in front of your family now, what will she possibly do in the future around your friends and others that you care about?
4) If she can't accept you for who you are, is she someone that you really want to be with forever?
5) Most people end up having that deep-down "I'm in love syndrome" with their first intimate partner.
Just some thoughts... take them as you will.
