My long-distance boyfriend is planning on moving to LA for us to move in together. Can you help us figure out if we're ready?
You should already know if you are ready or not, you shouldn't need people, who don't know how your relationship is daily, to help decide that for you.
Unless you BOTH are ready for marriage, and a long term commitment, Do NOT let him move to where you are, and then be heartbroken and lost if you ever broke up.
Only make that move if you BOTH know EXACTLY how the other feels, otherwise, it may lead to disaster
