True, I forgot that it's in the nature for comic characters to have tragic relationships and romances. But there's a reason that Scott is usually at the top of biggest cads list, perhaps only beat by Hank Pym whose track record is really just marred by one single panel that wasn't even supposed to be drawn the way it ended up being drawn as. Scott, on the other hand, has multiple instances of caddish behavior.
The X-Men is a soap opera though especially during Claremont's run. Relationships and romances are a huge part of the story. Most of them have bed-hopped with each other.
