Is this appropriate?? Please help

Can someone please please help - I am so worried - can't think of anything else. I need opinions on this, because when I was young I was abused by my father, so I think that has clouded my judgment on what is appropriate and what isn't. What I mean is I am thinking that I might be thinking it's inappropriate when it isn't, because I shy away from any physical contact. OK, this is the thing. Is this ok or not? An adult son (35 yrs old) is sitting on the floor watching tv, with his mum sitting behind him on the settee. His shirt collar is low at the back, and she starts tickling and stroking his neck and back. She did it for about 20 minutes, and also his arm - putting her hand up his sleeve to get higher. She then sat with her hand resting on his shoulder. Am I going mad? Is this ok? Because to me it isn't - I couldn't believe what I was seeing and felt sick and hot - thought I was going to faint. But am I just reacting like this because of my dad - maybe it is totally normal?? Please someone help.

That is totally wierd! I wouldn't say that this is appropriate behavior at all. The 35 yr old guy may think it is ok because he is used to it, but I doubt many mothers are still showing affection in this way at any time after puberty. Sounds like you've had a tough time yourself, but your instincts are probably more right than you may think.

well i just don't know what to do then - this is my partner of 4 years.

when they start doing it, as in the strokey thing, maybe look at them with a mixture of disgust/confusion/wretch a little bit If they say are you ok? say you are highly confused to why what is happening in front of me is happening. Maybe then they will both see its very wrong
