He's a bastard for not leading his partner on?

no, he's a bastard for doing it on a holiday.

Depending in how OP is, being around friends and family may help her cope better.

I bet you have obsolete no bloody idea what was going on. Stop judging the man and thinking you know the situation.

But to do it on a holiday AND there 3 year anniversary. No offense, but that seems planned, especially the time stamp. Which is shitty, then again, as someone else has said, OP could have well deserved it.

I don't think it's gonna be that easy to recover from having a three year old relationship ended, especially since it sounds like it came out of nowhere to OP. Having family unintentionally gouge that wound deeper the entire day is gonna make it worse.

Yes, OP will get over it in time. That's not the point though. The point is that instead of spending a happy day with her family, she'll be spending a day being upset minus who she thought was a family member, with the rest of her family asking about him.

That's not necessarily true. I was with my ex fiancé for almost 4 years when he broke it off. That was August 2015. I'm still not over it. No dates either.

You are really bad at comforting. If that is even what you are tying to do?

16 is also really bad at typing. I'm still not entirely sure what that comment is supposed to say.
