As you look across the couch at her, you start to feel anxious. You feel bad about effectively forcing the two of you to stay in tonight, again. While you are always appreciative of your partner's efforts to take your feelings into account and help make sure you're socially comfortable, you sincerely worry that you're holding her back from enjoying a more fulfilling relationship.
The reality hits you over the next few days, and you spiral into a very deep low. You withdraw entirely and outside of work, you don't leave your apartment. You can't stop replaying the failures you made with her over and over in your head, wondering what could've been if you weren't such a fuckup. It's going to take you a long time to get over her.
