<human>: There was drama in my friend group which ended in distance between my friend, lets call her C, and I, E. She felt a little excluded I guess and didn't like that some of us were drinking, small stuff that should be resolved. However, we kind of got over it and are very friendly in person. She will tell me all the time she misses hanging out and is very friendly to me.

However, when I have offered to hang out, something always comes up and she has rejected. I found it odd but I didn't consider it intentional. Tonight however, my friend and I wanted to be nice, so we invited her to grab some food at this Mexican place. She was really excited in person that day. Later we texted her, and she was really evasive and rude as she was with another friend and said they didn't want Mexican. So I ended up going with my other friend, and lo and behold, C and her friend are there eating. They awkwardly see us, smile, and get out of there as soon as they can. 
I knew things had been uncomfortable but C and I have been pretty nice to each other and earlier she seemed excited to go eat with us. The fact she thought it was ok to do this to me just felt really rude and hurtful. Should I just be done with her? I feel like going out of my way to confront her is a waste of time, if she is the kind of person who thinks its ok to treat someone like that. I guess she still has contempt towards me or something?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Drama happened between my friend C and me, things have been patching up and we have been friendly recently, I ask her to dinner she first is excited, later rejects me over text then shows up at same restaurant with someone else
