Hey there. It sounds like you've given this relationship a shot a few times now, and yeah, walking away might just be the best thing for you. It's clear that you have feelings for her and that she is unable to keep the relationship platonic on her end, so nobody's boundaries are being respected at this point (and it sounds like they're probably wishy-washy at this point anyway). I think in order to keep your sanity intact you should probably work on meeting someone who can give you what you need instead of treating you like a right-now woman (if, in fact, a relationship is what you are looking for). Sorry this is happening for you. It's challenging when there's something good in our lives that comes along with so many strings attached. Hope it all works out for you somehow.
