DP's ex has a new partner who is going to be staying the night regularly when their DD is home.
They were in bed together when DP dropped of his DD at her house last week.
DP would like to meet the man.
His ex doesn't have a great track record for straight and stable partners (DP excluded).
EX has lost her temper and screamed and shouted that it is none of his business and that she is capable of making her own judgements.
Who is being unreasonable?
