I should start by saying my ILs are lovely. They are extremely kind and welcomed happy as a part of their family.
They live abroad so we don't see them often so they send cards to us.
They sent Easter cards to the family which we opened today.
Mine was signed at the bottom from mum and dad.
My parents died when I was a child and to be honest I was a bit surprised that it upset me as much as it did.
I'm torn between feeling grateful that they view me as part of their family but also sad and a bit odd because they aren't my actual parents.
DW wants to say ask them about it. But I'm not sure because I don't want them to be offended. I also don't know if when the initial emotion wears off I might actually be ok with it.
