One of my son's going thru something similar w long-time gf. Unfortunately, that's been happening to me lately, and I'm twice their age. However, I'm amazed that sometimes it really is more about him or her, not you, tho not always true. If there's something you can fix, fine, if not, maybe you'll just ride it out. Time will tell. I know this isn't very comforting. i know you have to make plans. Sometimes it's good to just breathe and step back a moment! I know that wedding planning and marriage are both quite stressful, tho wonderful, at various times. The best to you, wish there was an easy answer here!
