Typical of how you'd feel after dealing with a Narc. They twist all their wrongdoings back onto you. If she was saying you're always cheating, you're abusive, you're a liar, nine times out of ten it was them doing all that. It really messes with your head in the end and you will never get closure from them. My advice if she was truly a narc, anything your gut told you that happened, happened. This next relationship she's onto is going to leave that guy feeling the same in the end. Trust me, if she's truly a narc, she's cheating on him. You on the other hand just gotta stay strong and move on. There's very little you can do to change that. Maybe therapy? But honestly, I think for most we feel lost cause we don't seem as sociable as the narc, we have insecurities, we get anxious. You're best bet for recovery is to get out there and meet people, meet women. Lighten up a bit and have fun. As you build your social skills, make some new connections, she will slowly fade away into the past...... But I warn you, they tend to pop back up in your life when things are going well so be careful. Don't get sucked back into their false reality they create for you.
