Hey there. I hope you're all doing ok during this lockdown. I know all of our health is the most important thing.
Two friends of mine are mortgage-free. They are in the same group of friends. The thing is they both confided in me about this separately (one over fifteen years ago, one recently) and they pretend to the rest of the group that they're the same as the rest of us. I have to go along with their pretense even though I have never had any financial help myself from a parent or partner. I'm going through a separation at the moment and it's been very difficult to find a place to live without any financial help with prices as high as they are. Meanwhile, one of them is garnering maximum sympathy from the group because her work hours may be reduced! Little do they know, that she is mortgage-free and this doesn't have the same implications for her as it would for the rest of us.
I wish they hadn't asked me to keep a secret I don't want to keep! I wish the others in the group knew. I'm tempted to tell one of them. What would you do? Also, I feel awful for envying them their good luck but I think what bothers me the most is the artifice around it. One of them forgot she had confided in me once and starting moaning about her mortgage!! I gently questioned (because I'm a gentle sort, not confrontational, so the solution is definitely not a confrontation with either of them) 'do you have a mortgage?' and she looked like a deer caught in the headlights as it dawned on her that she had confided in me years previous.
Why all the pretense? Why pretend to be the same as the rest of us when they clearly are not? Why swear me to secrecy? There are numerous examples I could go in to of them moaning about money etc in a way that others don't and meanwhile, I'm always the only one in the room who knows how good they have it, financially! 
Advice welcome.
