My ex-husband is rich, and I’m not: I bailed with little money and a small home for me and our kids that I paid for, grateful to get out of the toxic relationship. He has a massive mansion house four hours away (he moved) and two holiday homes abroad, and a live-in GF twenty years younger than him. We have shared custody amicably for ten years, but our adult kids have recently both moved in with him and have said they will be staying there until he buys them their own homes nearby. I was not consulted about this, not even a polite heads-up. On the rare occasion that I talk to either of them (both early twenties), all they do is talk about their privileged lifestyle and the family unit they are creating as a foursome. I feel jealous and excluded, but also a bit annoyed with my kids that they are being quite shallow in following his cheque book. He's emotionally challenged and not very loving or affectionate, and they know that. Am I being unreasonable to feel upset?
