I've often seen Narcissistic traits in her but it puzzles me why she would be content with a guy much less attractive, with much less to offer and seemingly not even her type? She has been seeing him since the day after we broke up (perhaps even before) and expect me to "get over it" but when she saw a picture of me and a girl (just a friend) at the park with our daughter she flipped out. My ex is like a walking contradiction that is beyond hypocritical. I know she isn't that far detached from reality, I know her disorder isn't that bad because she's able to hide it for months on end. It's just difficult to believe she is acting out in this way still. It's like she created a whole different reality in her head to sooth her damaged soul. Eventually it will catch up with her.
Its not about that man... .I guarantee you what I offered[and probably you too] mine and would do (I would literally go work at McDonalds if she needed every dime I had, and while I couldn't then live the lifestyle I'd been living, I'd know why I did it and be ok) will outpace anyone she will meet in our part of the state, hands down there will be no equal in that department.
But I honestly believe that when they bump into caring people and not S* heads where they can't throw their arms up and play the victim they then seek not to find someone better as us NONs would do, or self improve, self introspection. They seek to find that role that is comfortable which can easily allow them to play the victim roll, where as with us giving and genuine people they really can't do that

. I guarantee you she's got some people and family members like mine probably do who see her writing stuff like "I need a loving dependable bf" and are just thinking UMM okkk

The one thing I'm glad I'm doing is not looking at my replacement wondering why is he better (because he's not)... I'm sad I didn't get an opportunity to work with her more and try and help her having been on this site, I'm sad I'll never know if she's safe or cared for or just being used, I'm sad she doesn't have someone who would give her anything she needed to be successful... .But I am not sad by her replacing me or bragging how perfect he is 3-4weeks later, because those decisions are made with no logic, no facts, nothing but impulse and sickness.
I'd just keep telling your daughter this, and yourself. If you know you did it right and while you made mistakes like any normal person, then it isn't on you bud.
