<human>: Hello,

A friend of mine at my university invited me to a christmas party later this month. I used to hang out with a group of her friends frequently, we were good friends, I enjoyed the time I was with them, and they said they did too. But then it just kind of stopped a few months ago. It was fairly abrupt.

They just stopped talking to me, or trying to make plans with me. When I tried to make plans with them, they said they were busy, but some other time for sure! I eventually gave up, and we haven't spoken since the end of august.

So this invite was kind of out of the blue. I wasn't good friends with the person who invited me, but she's good friends with the previously mentioned group, so they will be there. I'm not sure if I should go.

Give me the gist of the text in a nutshell
<bot>: used to be friends with people, they stopped talking to me for months, was just invited to their christmas party.
