Sounds asexual (the ace in aroace) to me, but not very aromantic (the aro in aroace).

Identifying your sexuality can be very freeing, don't let others identify you, only you get to draw conclusions about your sexual identity.

That said, your thoughts certainly seem to line up with aromantic thoughts

If you don't want to kiss your girlfriend or have sex, you probably don't really have a girlfriend and are just really building up to a horrible breakup. Why did you even seek out a girlfriend instead of just remaining friends if you don't have any romantic intentions?
