Your Sign and your kind of Love?

I'm a Libra but I found that the Pisces 'kind of love' fit me better. Could be because I'm unsure of that last sentence for Libra, "Love is an open situation". Not that I completely disagree with it. Just a little iffy about it, is all. I think it's the sacrifice in love mentioned in the Pisces kind which made me choose it. I don't even have any Pisces in my chart...
