What do you think?

So I've been dating this guy for a year now. We were supposed to start living together next month and talked about having a baby soon. Our 1 year anniversary is this Friday. He just told me that he accepted an invite to a Thanksgiving dinner from a woman he has some business connections with. She's taking him to her boss' home for dinner. I was so hurt he stood me up when I told him I wanted us to spend the holiday together. I just broke up with him.
