Alright so here's the long story...
We moved to Boston and became pretty great friends with this couple. About 9 months later they move to Texas for a job. We are all sad but hopeful that we'll hang out again. 3 months after that I get engaged. They of course made the list of invitees, even tho they lived far away. We were generally talking and txting and staying in touch. We even sent them a save the date a few months ago. Now I've learned through facebook that the couple is no longer together. He's moved on to a new woman. Haven't talked to either of them about it. Neither of them aknowledged that they recieved the save the date or reached out to us.
At this point, should I really be sending them an invite to the wedding?
