Is this girl just using me to fill the absence of her boyfriend?

I met a girl a few weeks ago and ever since we’ve been spending a lot of time together. She invites me to yoga with her, we go out for drinks, etc. She also does stuff like takes lots of pictures of me. She just recently started inviting me over to her apartment and asked me to come over tonight, saying she’s “sad about her relationship.” I know she has a long distance boyfriend so I’ve never made a move or anything. Does it sound like she’s using me to fill the absence of her boyfriend or does she think something might happen between us?
