My fiance got me an engagement ring a month after I first proposed to her. Even before we began officially dating I mentioned that my grandfather's wedding ring would be the only one I would want to wear. She's told me since I proposed that she feels undeserving of her ring and bad that I emptied my bank account to get it. She loves it and we talked about what she wanted many times, and every time she asked me what I wanted, I would state my grandfather's ring meant so much to me and that's all I want.
She surprised me with a pricey ring, that doesn't look bad, but I don't want. When I mention that I'm having a hard time dealing with it, she says that I need to suck it up and she mentions returning hers as well. Should I quietly suck it up, or try to get used to it or continue this conversation that seems to be getting us closer to our first real fight?
