Does that even exist?

I feel like my gf doesn't love me the I do (which I always knew).

I feel like she "cares" about me because, if I'm not happy with her (because she fucked up), I don't make her happy.

So, she "cares" about me, not because she "loves me" but because I make her happy if I'm happy regarding her. But deep doing she doesn't give a shit about me, just about what she get from me by being sad/happy. "How she thinks:"

I'm he's happy with me, he makes me happy yay!

I'm he's mad/ignoring me, he cannot make me happy, therefore I try to make him enough happy towards me so he can make me happy again, but I really don't care if he's happy, just if HE makes me happy.

Is this normal female "love" or I just have a fucked up gf?
