I am the middle child between two sisters and there is 5 years between me and my older and younger sisters.
Me and my younger sister both own a three bed semi detached house, she lives with her husband and I live with my girlfriend and son who is 18 months old. The week after my son was born it was announced that my sister and her husband had bought a house. And we were all happy for them but then it turned out what had actually happened was they had approached my parents and asked them to lend them money so they could buy an old bungalow, raise it to the ground and build a new house and we were told that they would sell their current house after they have moved into this rebuilt house and then somehow pay my parents back the money they borrowed but everyone seemed vague about how that would happen.
Fast forward to now and they are almost ready to move in but the buyers of their current house have pulled out but it is not affecting any chain. Anyway we have now discovered that my parents have told them not to pay them back so with everything included have basically gifted my youngest sister half a million pounds or in that region.
Obviously this is now creating resentment for me and my older sister. It has been mentioned in passing that me and my gf are struggling for space in our house but we are having to make do until we can afford something bigger but that wont be for a number of years yet.
I think I am feeling most resentful because not only has my sister and her husband been gifted a house but when they had a big extravagant wedding back in Summer my parents paid for 90% of it whereas I am working all the hours I can and after bills and nursery fees etc I am having very little to show for it whilst my parents have given all this to my little sister and don't seem to understand why I am annoyed.
This is also not including that the money they have given my sister and her husband over the years with other stuff whereas I have basically been left to fend for myself.
Am I being unreasonable or am I justified in feeling annoyed?
