Dream of girlfriend

I heard my son, who had not spoke to me or seen me in six months, he was at the front door with his daughter and his girlfriend whom i have never met i open the door for them hearing him say i probably wont open the door for him when i peeked out the window and seen it was him i was very happy and surprise when i let him in i went to give him a hug but he walked away from me he kept his head cocked so he wouldnt look at me at the same time he was walking around like everything was okay i was trying to get his attention and his daughter was saying hello to me but i was trying to see what was wrong with my son
