Asexuality

Okay so my girlfriend is asexal and I'm sexual. I'm okay with her sexual orientation. But she doesn't want to hug hold hands cuddle kiss on the check etc.  and I like that stuff and I'm trying to understand and I'm trying to be supportive. But I feel neglected.  I feel like she doesn't care because she doesn't show it physically or mentally. And I care and like her a lot. But I just feel like she doesn't care.
