<human>: Can you give me the gist of the text in a nutshell?

I've had feelings for my friend for a few months now. She's completely aware, but we haven't let it affect our friendship at all. One day I opened up and told her how I felt, she didn't reciprocate and we just moved on. We talk about it from time to time but the conversation never gets weird or awkward. She currently has a boyfriend. He's cool with her and I being so close and hanging out by ourselves, he respects and trusts us both. He does not however know about my feelings and does not know she wants to get an apartment with me. I'm conflicted by this because I'd prefer she be open and honest with her boyfriend (even though I have feelings for her I want nothing but the best for her relationship, she deserves that happiness and he gives it to her) but at the same time if he knew he would probably be upset and feel uncomfortable with how close my friend and I are.
So, my I guess my question is this: In your opinion or experience, how do you think this would play out in my part? Obviously you don't know us well enough to know but I suppose you can have an idea.
Also, should I encourage her to tell her boyfriend? This is kind of a big deal and "I want to move in with the guy who has feelings for me." seems like it might cause some issues for them. She wants to tell him eventually but this is kind of a big lie and I don't feel super comfortable being a part of it. It feels like collusion and if I were in his shoes I'd be upset.
<bot>: I have feelings for my best friend and she wants to move in with me. Should I? And should she tell her boyfriend?
