Maybe you can try and talk to her before she leaves and rather than just ask her out, be more open with your feelings and let her know that you have an interest in her and while you know she thinks you are lovely, you would like to know if perhaps she might have an interest too at some point. This way, you are trying to find out more and if she says she isn't interested then at least you know.
That works fine too and it keeps it open should she have the desire.
It definitely is but it sounds like you are handling it well and doing the right things. She knows how you feel so give her that nice parting message and then let things play out as they will.
My pleasure. Be well. Be strong and be open with her and I hope it all works out for you. Please take a moment to click the rating tab to rate my support. Thanks so much.
