am being I to clingy or is she pushing me away or losing feelings?

Well, this incident, without any sort of point of reference, leaves me making some assumptions. Number one, maybe you guys have not been together long. Number two, the group is not used to seeing you too together. Maybe she is not sure what the group will think so she’s is hoping you two will act a little more independently within the group rather than act as a couple within the group. It sounds like you are comfortable or not worried about what the group thinks of your relationship. Perhaps she is worried about what the group thinks. Part of being young, we tend to worry very much about what the group thinks and we tend not to be very comfortable in our own skin. Maybe not you as much but your girlfriend may not be comfortable in her own skin. At some point she needs to not care what the group thinks because it’s influencing her behavior. As we get older, we all stop caring as much what the group thinks. Give her a little space. And see what happens. if she’s feeling pressured to appear as a couple within a group that is not used to seeing that, then she may act a bit erratically. Again, without full context of your relationship, and how things normally are, this is the best analysis I can provide.

If I feel I'm being pushed away
I will stay away

You should probably too

She could be pushing u away

sounds like she's pushing you away

That shit is over.
