JC… can you answer my question, please? Does “available to someone else” mean available for sex, dating, or just hanging out?  Did she invite you to the concert or are you just unable to go?

It’s one thing if she’s saying she’s available for dates, sex, and things like that with other people or didn’t even invite you to go with her to that concert but it’s another thing if she’s just wanting to take a friend to a concert since you aren’t able to go with her. So those details are kind of important.
