Women's tendency to be jealous of another is only nature and when the PA becomes too good n too close, it surely sounds hanky panky going on ... and there husband who want the mistress n PA n wife n family all at one go .... the world is this complex.
So its up to you which direction to go of which all may not be easy. But always keep in mind whatever you do.. your kids will be affected.
HB never ask her out or they went out only of them as I knew these.
I admitted I felt jealous.
In facts, HB don't like to hang out with entertainment. He is those homely type man. He will go home after work. He like to be alone and rest after a long day working outside
