Something about SLY doesn't sit well with me.
So he dumped her* and he a family now and she's stalking him and wants to suddenly show up to his place uninvited? (Glenn Close/Fatal Attraction vibes)
But she decides against it and instead she's gonna find someone like him...someone who's going to dump her like he did...causing the cycle to repeat.

Guess she gave you things I didn't give to you = dumped
