M–I am concerned, 3 years is a pretty long time. You see he and his family as arrogant. Your Mom taught you better values. You sound like a kind likable empathetic person.

If you look ahead and think about having a family with him-what conflicts do you see with raising children…. would you be comfortable with him being the father of your children and raising them with you. This personality trait of his could be a lot more than annoying when your children look to you both for guidance.

Be good to yourself.
best of luck
