I posted a thread to this subreddit that has some context to this. To summarize up to this point: I like a girl who is in a co ed tennis league with me. We just became friends and recently started talking more consistently (weekly at least). She got out of a relationship less than a month ago.

So - she invited me over to her place before our league to "hang out and play video games". Of course, I agreed. She invited her best friend as well so it was 3 of us. It went very well, her friend and I got along well, and we all had good conversation for a couple hours.

She drove me back to my bus stop after the game and on the way there told me that I should come to her volleyball league on Sundays with her other group of friends.

Another note, we had a happy hour I couldn't make and she texted me wondering where I was.

I really like where things are going, but want help breaking down why she a) invited me over abruptly, b) invited me to meet and hang out with her other friends at volleyball. Of course, I am taking these as good signs, but want to dive deeper into it.

Also - her ex boyfriend situation. She mentioned to me that her and her bf broke up recently and that she didn't really want to talk about it. But she still seems very hurt/emotional from it by the way she said it. How do I approach this? Should I just ask her out anyway because of these subtle signs? Can I ask her best friend for advice?

In general, what would you do next, and how would you perceive all of this?

TLDR: Girl I like invited me over with her best friend. Went well. She just ended things with boyfriend few weeks ago. She invited me to another league with her other friends. Do I ask her out now, how to perceive all of this?
