Dating someone your friend likes
If you need to vent about one of them, find a neutral party. But don't assume she doesn't want an invite if you haven't asked!
In general, allow your friend and your sweetheart to decide how much contact they want with each other, and don't push them to associate if they're not into it.
They believe this is something everybody knows, that they're just following the rules.
What I've noticed, though, is that every person I've heard espouse this worldview was straight.
This has nothing to do with some kind of Eternal Dibs situation, and everything to do with the fact that, by choosing to build a relationship with someone who treated her horribly, you're telling your friend you don't think what he did to her was all that bad. There are lots of people out there who are just as good in bed and haven't traumatized anyone you care about.
Set the precedent that people who are awful to your friends are people who don't get to see you naked, and your life will be the better because of it.
Even if you meet someone to whom you think you have no previous connection, a 10-minute conversation almost always reveals that she went to high school with your college roommate, used to be on a volleyball team with that girl from your book club, and had a six-month stand with your favorite barista.
Trust that your friend is happy you've found someone you dig, not plotting to sabotage your love.RELATED:22 Reasons to Stop Worrying About His Ex-Girlfriend17 Things I Wish I'd Known About Getting Over an Ex When I Was Younger11 Reasons Why He Broke Up With You Follow Lindsay on Twitter.
