Background-
2 siblings and a DM.
Sibling 1- public sector job earns 50k, has 1 DC and is the sole provider for them, has a mortgage on an average house. Has a strained relationship with DM, sees them approx 5 times a year.
Sibling 2- built up property, no DC, has 5 mortgage free properties rented out (these are not the main income source). Has a very positive and supportive relationship with DM, sees them multiple times a week.
DM- has MH struggles and has relied on DC off and on their whole lives. DM has always lived in rented housing.
Siblings have an amicable but not close relationship, stay in contact via message etc. Talk if they bump into each other but rarely call/don't spend birthdays & Christmas together etc. Siblings and DM all stay in the same city within about 5 miles of each other.
Sibling 2 has decided (no conversation with sibling 2) that they are giving DM one of their flats. Sibling 1 thinks this is lovely. Sibling 2 then calls (only phone call this year) Sibling 1 to explain the rent they will lose will be approx 1200 a month. This point is laboured over 2 phone calls. DM then also mentions this to Sibling 1.
Sibling 1 is starting to feel under pressure to offer to make a monthly contribution to the lost rent. However, they a) can't comfortably afford it. b)don't want to c) don't think they should as there was no discussion/joint decision making process d) the lost rent is not a main source of income e) would rather use spare money to build security for their DC.
I am Sibling 1. Am I BU?
