Summary: I'm upset my friend keeps canceling our altering our plans to hang out with other people.
To give some context, I met this friend in undergrad, and we ended up moving to the same city. I'm socially awkward, and she can tell.
In undergrad we hung out together and even traveled together once. (She made it clear she had asked a bunch of people before asking me, but I didn't mind since we had just met.)
But even after becoming friends, she's done some things.
She's invited me to get a senior apartment on campus with her. I immediately told her okay, then a day later she told me she's rooming with someone else instead. (She didn't mention she was asking multiple people.)
She's invited me to hang out, but after getting there I learned she invited other people and she kind of ignored me. (She didn't tell me it'd be a group thing. To me it felt like a better friend suddenly had time, and she felt bad about canceling on me entirely so agreed to let me be the third wheel.)
She's told me to my face I'm "convenient" for talking to about personal stuff since I'm friendless and can't gossip to anyone. I like being there for people but dislike being called "convenient." I told her that, but she didn't care.
My first weekend here, we agreed to go to a movie and dinner together. After the movie she suddenly told me she's going to hang out with someone else instead and left me there. I ate dinner by myself...
This weekend she asked me to hang out with her again. I told her I'm free, then she suggested hanging out as a group with another person. That other person said she's busy. I assumed us two would still hang out and offered some fun suggestions, then she texted me back she's going on a date instead, even though in this case I'm the first person she texted... I feel like I'm not interesting enough just by myself? I'd chalk it up to a simple miscommunication except I feel she's constantly cancelling or altering our plans to hang out with other people.
I understand there are best friends and backup friends and occasionally plans unavoidably get canceled, but honestly I feel horrible after interacting with this person. I've confronted her casually and she seems to get it but doesn't seem to actually care.
Although I'll say, when we do end up hanging out, she's friendly and talkative.
Am I just being too sensitive? Or am I right in thinking she's subconsciously taking advantage of the fact I'm socially awkward and thinking of me as a backup friend?
