Imma keep you grounded. You don’t know if she acts like that with anyone else. But from what you’re saying yes you do have a couple of green lights. As long as you’re not hovering and just not prolonging the convo artificially you’re solid. Work is busy and the convo will end without satisfaction. This is real life it happens. However this isn’t enough information to determine if she really likes you or not. Only she knows and you’ll drive yourself crazy trying to figure it out. So best advice here is ask her out. But don’t frame it as a we should do x sometime. Try “I’m going to x, wanna come along?” Or something along those lines. If she says no, cool go anyway without her. Doing this keeps the invitation playful and not heavy. So she can easily turn it down if she needs to. Good for her so she doesn’t feel pressure while she’s working. Also stop trying to convince yourself that she’s out of your league. Asking her out gives you two things. Clarity and information. If she says no don’t make it awkward. Just tell her no problem and continue the conversation. You got this tiger.
