Using my current relationship as reference, yes. If you have confidence in what you have with someone and you believe it can last as long as you live and you truly believe that, then yes. If any part of you doubts the relationship or isn't sure, then no. I would move for my boyfriend now because I truly believe we will be together forever, everyone in my family approves of him and we have already discussed moving out on our own together. We both have the same timeline of how we would like things to work out (or a rough one at least, things can change), and we both know we have each others back in trying times. If you can say the same for yourself without second guessing it, then I'd say you can too.
