The amount of time she touches you for is an aspect of what determines if the touching is flirty or friendly. Was the touch a quick brush or does her hand linger for a few seconds? Where she touches you could be a sign of what the touch means. Touching your shoulder might be something she does with friends, whereas touching your hand or face could be a sign she is interested in you. Notice if she reciprocates your touch. If you give her a side hug and she leans into it, she might like you. If she seems uncomfortable and pulls away from the hug, maybe not. [1] X Research source

If she says, “Tanner bought me roses yesterday and we are going out to dinner tonight! He is the best boyfriend,” she probably does not like you. If she says things like “Tanner and I got in a huge fight last night because we never do anything together,” her heart might not be all in the relationship.

Try saying something like, “I know you have a boyfriend - and I don’t want to get in the way of that - but I just wanted you to know that I have developed feelings for you. I completely understand that you are committed to someone else, but I want you to know that if you weren’t I would want to date you. ” Give her plenty of time to think about what you tell her and to navigate her feelings.
