My boyfriend and I may not be together by Thanksgiving. When the curious people ask why he did not attend with me, what should I say??? I know it will be hard to talk about it.

Just say he couldn't make it this time. When you are ready to talk thats when you do. Until then it's no one's business.

I would say the same thing Yin said, that he couldn't make it. It's still the truth without revealing anything personal.

I would just say he had other commitments .. You don't need to explain, it's no one else's business
