When I first met my wife 7 years ago, she was trying to maintain friendships with a couple of ex's, including the one she turned down to be "official" with me.

I ignored it and it went away within a year. I was confident and secure that she wanted to be with me, and that any efforts these guys might make to woo her back would be wasted energy.

In weaker moments, I just figured "Well, if they get her back, that's that and I can get back to friends/bachelorhood.

That's the key...don't be so crazy for someone that you care what happens. Let life happen the way it wants and if it's meant to be, it will be.
