Hi all! I'm in bit of a predicament about what to do... I have these two coworkers that I occasionally hang out with outside of work, along with their SOs. I ended up mailing one of the couples a save the date, but not the other one because frankly I was worried about how drunk that coworker would get and cause a scene at our wedding. But I did ask for her address with the intention of inviting her several months ago. Fast forward a couple of months, and things have gotten a little weird between me and the coworker to whom I sent the save the date. She seems more distant, putting on a front and frankly fake. Not sure why I didn't notice this before, but now I'm stuck. I'm beginning to have doubts about even sending an actual invite out...to either couple. Long story short-- what is the best way to go about this? I sent the save the date, but have no intention of mailing an invitation. Should I just not say anything or approach the person explain myself or tell them a little white lie? Also not sure if they've been in communication with each other about one getting a save the date and the other not having received one. HELP!
