Deal with the past
Before you can move onto your next relationship and trust that person, you've got to deal with the past, messy relationship.
That means no more drunken texting and calling your ex, accepting what happened, and coming to terms with it.
Remember, it takes time, so don't be hard on yourself if you're still not over it a few months later!

"Remember that this new person isn't your ex," says Christine. Just because your last man was a rogue, it doesn't mean to next one will be.
