Most Helpful Girl
No, it's not! She shouldn't be demanding for you to do anything besides respect her and honor the relationship boundaries you established. I have had few boyfriends who did nice things for me like that, and the last thing I would do is demand more of it. She's not good for you, and her demands will probably get larger in time. Dump her.
HOWEVER, once, I had a boyfriend who was really cheap and bragged about how he bought his ex a $150 dress and his other ex "made" him pay for everything (dinner, etc.). Mind you, I took special precautions not to make him spend money (free movie tickets, etc.) and it hurt that he treated his exes better than me, so I told him this and said "well, what about me?" Then he gave a HUGE guilt trip and later complained about giving Christmas and birthday gifts (as I did for him). This is part of the reason why I don't want a guy spending money on me; he likely thinks I'm not worth it, and I look like a huge beeyotch for wanting to be treated as well as his exes (after he brags about how much he spent on them unsolicited).
