I was idly thinking of past relationships and their demise, and the most recent one particularly.
I was seeing a man for about 11 months, everything fine except for one major thing. He was clearly besotted with his 22 year old son, and although they lived apart, they spent every weekend together either following a sport or amateur coaching (DF) and playing (DS).
I was a bit miffed at not having any weekend time with him, but knew this was non negotiable. His reasoning was that one day his son would not want to spend that much time with him, so he was making the most of it. The son had a LDR, and dad took him to see his GF, and socialised with the GF parents, also took his son and GF out when she visited son. I was never invited to meet the son, although he talked about him constantly - even to the point of when we ate out, telling me what his son would eat if he was there 
After 11 months of this, I asked if his son would like to meet me. He said "no, why would he?" I was a litle shocked, and said "out of curiosity if nothing else!"
He said his son didn't care who he (dad)was seeing.
I felt completely sidelined, considering the amount of time he spent with me talking about his son. Good enough to listen to all the talk, but not good enough to meet his son. I then began to wonder if in fact he wasn't spending as much time as he said with his son at weekends, and was seeing someone else instead, and he was worried this would come out during the meeting.
I pushed to meet the son, and the man ended it with me, saying "look, let's just be friends........"
We tried this, but the mistrust I felt was too much, so I went NC.
Just wanted opinions on this. Not pining, merely interested in other's views.
