Firstly nobody and nothing ( except maybe chronic illness and constant pain ) is worth killing yourself over so put that outta your head straight away. As long as you are breathing and have reasonable health things can always get better.
I don't think you should move apartments yet because you are putting her on a pedestal and she is maybe still looking around and not sure about the relationship. She was incredibly thoughtless saying that to her ex in front of you and even if she only meant it as a friend it was very tactless. Love ( and even very close friendship without love) means sharing everything good and bad. I think the fact that she doesn't do this and with the other things you should proceed with caution. Don't use pressure tactics to get her to want you. If it happens it happens and SHE will COME to you. You are going to make yourself ill over it. Back off for a while and see what happens. Good luck.LOve and peace
