There are other reasons why this guy was looked at in a bad light.
I don't know how much of this is out there ,but I know some is not.

But when Salvie was down at the shore he had one of the hottest girls around here.( Before during and after the wedding that did not go on) And many of the guys his age at the time wish they had.I am not saying that had everything to do with it .But when these guys want what he had,they will make stuff worse.(This girl is still hot")

But this may have ,while he was to marry Chuckie's kid he had a girl in Philly that everyone knew about.
Then when he was down here he had this girl that everyone knew about .
He did not hide any of them from the guys, and or Nicky or Chuckie.

Salvie would have everyone over and sit out back on the deck and on the boat that was tied to the deck / dock.
Now of course the guys would talk and the girls would talk more .This was all in the faces and family members of Chuckie.

I don't know if this is in a book ,but salvie was a dealer and he was into meth" and he was with all kinds of people that Nick did not want him with . He was able to make these contacts from doing work for Nick.He took it apon himself to get real deep in dope.

I am not saying anyone should be killed for this. But in his life that he chose" he knew that the things he was doing was going to come back on him and this is why he did not push back .He knew and accepted that he did wrong and he knew that "greed" got the best of him.

This was all possible through the work he was doing for the family.
He stopped hanging with Phil and a few others that he would normally would before he dumped Chuckie's kid.
This made many suspicious when a guy drops out of his regular guys.
I am not talking about his crew ,I am talking about the guys he looked up to and hung with.
