I have fallen for a girl at my gym, she is straight as far as I know, we have had some contact back and forth away from the gym but it's me reaching out to her, this could be because I have just got out of a relationship, I don't know what to do I feel like there is something between us, stares and being near me, how do I know if she likes me is there anything else I could do to make her know and see if she likes me.. I can't come out and tell her in case she doesn't feel the same and I ruin things.
