Isn't your daughter the one that really has hard feelings toward your H? If that is the case, then I would say that it's best to not have H there......but it's up to the boy friend to make that decision. So, why don't you discuss it with D's boyfriend and see what the dynamic of his conversation with H was.
And definitely take your male friend as you already planned! If H shows up unexpectedly and sees you are not "pining" so much the better! But if you know in advance that H will be there, then I would do your male friend the courtesy of informing him of the situation, and let him decide if he still wants to join you or if he would feel uncomfortable in your H's presence.
And I love euchre!!!! H and I used to play that with friends all the time! My H grew up playing cards with his family. That's what most of our dating time consisted of. Movies, Restaurants, and playing cards every night with his brothers and their girlfriends. I was too young to go to a club or anything like that. I loved that "quality time" with family. That's part of why I fell in love with my H.....his value of family.
