@ehBeth,
It was a business conference that just happened to be on her deceased husbands birthday I didn't plan it that way. At first she wanted to go because one of her best friends lives in the city the conference was held in but I think once she realized the date she changed her mind. I didn't even know it was her deceased husbands birthday when I scheduled the trip as I can barely remember my 8 siblings birthdays but I guarantee I'll remember that date next year....
And I never once said anything about her giving up her inlaws in fact I went to one of their kids weddings. She goes to her inlaws quite often and I never say a word, I just think that it's weird that she celebrated his birthday with them when she's been with me for nearly two years and we've been talking about getting married and buying a house together.. Although you are reconnecting with one of your ex's from your teens family, are you going to celebrate his birthday with them?
