My GF[20] got a tattoo of something that represents me[24M]. I don't like the idea.

So yeah, my girlfriend has had this idea of getting a tattoo for a long time. At first her ideas were things like a Lotus Flower or a mandala. I thought they were cute, and encouraged her to get a tattoo. So yesterday she told me she is gonna meet with one friend of hers, this friends also happens to be a tattoo artist so i asked her if she still has the idea of getting a tattoo, and she says maybe, then she tells me that she has a surprise for me, proceeds to show me a drawing of a fruit. Now this fruit has a special meaning for both of us, because it was present the first time we met, and it has been something that somehow "represents" our relationship. I didn't like the idea at all, basically because we only have been dating for ONE year, and i would NEVER do something like that, and, although i didn't want to hurt her, my face was an open book. She got a little upset, said that she wasn't getting my name tattooed or something like that, because these tattoo just doesn't represents me but the things she has learn being with me, such as loving someone more than your self and making sacrifices for your partner, etc, and even if things don't work out between us she will still like it (i'm not sure about that).
She didn't expect my reaction at all, and felt a little sad and disappointed. I told her that if she really feels that way, she should get the tattoo, but it had to be something for herself, and i didn't want to feel responsible if she somehow ends hating the tattoo. The drawing was cool (it really was).
Yesterday she got the tattoo, it is big, it covers all her thigh. I don't want to feel responsible because she got the tattoo despite my reaction and our conversation, but somehow i feel this pressure, and i wish she would never have got the tattoo.
Am i being and ******* here? Also i feel like and hypocrite because i should have told her my honest thoughts, but i just couldn't because seeing her sad makes me feel so guilty.
tl;dr: Girlfriend got that a tattoo that includes me. Am i supposed to be ok with it?
