Sorry, what do you mean silly? I met someone on PlayStation as a teenager and 10 years on we're happily married, nothing silly about meeting on consoles?
As soon as she started attending parties, trips, fake tan etc etc you could tell Sam didn't fit into her life anymore, she didn't even try to include him. She never took him on any trips or events but within months of breaking up with him she was with the new one and taking him everywhere. It came across, to me, that she thought she was too good for Sam.
