But you know that this isn't real life- there are good and easy things, and there are those that take effort, and that her wish, to not do anything that takes work, isn't realistic. It may work when someone else is carrying that for her- but even so, the other person is human too and may have their own limits to how much they do that.
I agree 1000%. On this site, I've posted numerous times how I think a victim attitude is the worst part of BPD. But in a close second comes unrealistic expectations in my opinion. The pwBPD in my life holds other people to impossible standards, which sets herself up for constant disappointment. It's strange that she doesn't seem to hold herself to the same standards, but this is when she calls on her victim narrative to serve as an excuse. Generally speaking, I think she holds somewhat "delusional" beliefs about what her life should look like. That includes being taken care of by other people. She THINKS she's looking for a spouse, but I think what she's really looking is a fantasy Prince Charming, to sweep her off her feet, adore her, treat her like a beautiful princess and lavish her with gifts and spending money. But that's fantasy, not reality. Spouses generally have to work to earn a living, and do all sorts of things they don't want to do--clean toilets, get dinner, fix appliances, save money for a rainy day--which "detract" from the fantasy. And let's face it, people can have bad days, get sick, feel exhausted after a long day's work. Maybe they are snippy sometimes. Maybe they need some TLC, or at least be cut a little slack, such as when they are ill, have been injured or have suffered a death in the family. Normal spouses understand that, but I don't think pwBPD do. They think they have empathy, but in reality, I think they don't take anyone else's feelings into account, not even their own children's. They have all sorts of impossible expectations of others, but very low standards for themselves.
And so I think it's logical that your ex will try to find someone else right away. She's hidebound by her delusional thinking and low functioning, and my guess is she'll tell every potential suitor how horrible you were, just to get sympathy and attention. She might finds someone to "rescue" her. But really she needs somebody to take care of her (at least that's my guess). Maybe her family will, maybe a boyfriend will. Was she low functioning in your marriage? Did she not pull her weight in the household or with parenting duties? Did she overspend? Those are classic BPD issues. I'd say, try not to take what she does so personally. I know it's hard, but if you spend some time reading here, I think you'll see there are classic BPD patterns that have nothing to do with you, and everything to do with delusional thinking and BPD acting out.
You control you. You can't control your ex. You focus on making a life for yourself and your kids. You and your kids deserve that.
All the best to you. Hang in there, you've got this.
