To the OP, I feel your pain man i really do, I've been there before myself. You obviously care about this girl but I think deep down you know what must be done. First you came here to ask this question most likely knowing the kind of responses you were going to get. I mean...Did you really expect to get unbiased opinions from collectors- Of course were going to tell you do dump her and move on. I hate to break it too you, but if she is not about "wasting" money and she views your collection as a waste of money your screwed. She will always resent you for buying figure/statues or simply spending any money of any kind on yourself. She will hold it against you anytime she doesn't get what she wants or any time you have an argument. Some people just have too much baggage from their past, and its not worth your time trying to fix them- definitely don't change yourself for them you get one life, enjoy it. If you want to be a hero or a good guy be a big brother for a kid, rescue a dog from a pound, donate your time to charitable causes- but whatever you do don't waste anymore time on a woman like this she will drag your ass down.
