I invited my boyfriend of a year to go to Vegas with my kids and I. He had said yes but when I checked back in with him he said no he could not because of work. Trouble is he just told me what his vacation days are and those are the days we would have been gone. I think this is him not being serious about us and he thinks I'm picking a fight. I don't know what to expect in this situation because I've never had a boyfriend and had kids at the same time. What's the right thing to do? Also, he hasn't introduced me to his son. He made a point of meeting my kids and comesto eat with us now and then though. Looking for perspective.
