More than likely, her eating off the same plate as you means nothing. She didn't want a heavy meal, so she shared with you. Don't mistake her being friendly for flirting. There's a fine line and it can often be hard to tell the difference. Friendly and playful girls often get mistaken for being flirty when most of the time, it's just their personality.
One way to find out if she is into you or not, is to text her. You could say something like "hey sorry I'm just now texting you, I've been busy the last few weeks. But I had a great time at lunch the other day and would like to do it again!" And gauge her response. If she wants to do it, she could possibly be into you or just consider you a good friend. Hang out with her and feel her out. Casually bring up her relationship and ask how it's going. Flirt with her but be very respectful of the fact that she does have a boyfriend.0THIS IS NOT RELEVANT ANYMORE
