My Dad is Gay

I go visit my Dad who has recently separated from Mary and discovered he has a 13 year old son. When I get to the hotel where we are staying (a very nice hotel where I have stayed in other dreams) Dad is there with a "friend", and he gradually comes out. I am okay with this until I see the two of them sitting next to each other and his friend's hand is on my Dad's leg. I talk to my new half brother about how I want to be okay with this, but it just seems weird, and it makes me feel bad that I am not supportive of my Dad.
