You become obsessed with every phone call, jump when he says bonned family porn videos, and change from the attractive, interesting woman who intrigued him into someone needy and clingy he feels pressured to check in with.

But if you can't stop focusing on the potential future turmoil, you should rethink moving along.
By sprinkling in comments about sex and dating into your conversation.
