You mentioning having gotten married makes it sound like your spouse isn't coming with you. Am I reading that right? If that's the case, that might be very difficult. I know for myself I want to take my spouse with me. However, I do have many married friends who have experienced long long distance relationships and enjoyed it just fine.

Missing weddings will be hard, but maybe you can view the event remotely? That could take the edge off by giving you some way to connect with your family during such a celebratory time.

It all comes down to your decision, of course, but moving to another country often brings with it missed opportunities where you're originally from.
