Damn it

Be her friend if you’re mature enough, and put her out of your life if you aren’t. You suffer when you are hung up on someone. If you are a “double agent” claiming to be a friend but looking for your opportunity to slime into their heart, walk away. If you don’t look for or are closed off to other people and happiness, walk away. But if you can be a real friend, live your life and not plan what you do and stand in the way of your own happiness because you’re obsessed with this person- then sure. Be friends. Real friends. If something ever happens great. Maybe by then though you’ll have moved on and be happier with them as a friend.
