There's nothing wrong with managing expectations with your friends by speaking up about your concerns. If she's a genuine friend (who is interested in a mutual friendship) she'd make more effort with you when you two hang out.

Her being on her phone while out with you would have been a deal breaker for me: that's just plain rude and disrespectful (unless it was an emergency, than that's acceptable).

At the end of the day, if it really bothers you, just speak up and hope she understands. Her response will tell you where you stand with her friendship-wise. If she gaslights you, she was never really a 'friend' but just someone you saw occasionally.

If you have to chase after people to be your friend, they aren't really friends. Friendship is a two-way street.
