Name changed.
DP are engaged and planning our wedding, we're both very excited!
We've been discussing bridesmaids and best man and low and behold MIL has stuck her nose in.
DP's parents have split, MIL has a partner (10 years) and FIL has a wife (9 years). FIL has 3 step children our age that we consider family as DP knew them growing up before his dad married their mum.
DP's best friend is also his step brother now and he was considering asking him to be best man and I've asked DP's step sister to be one of my bridesmaids. We were discussing this with MIL, bad mistake.
AIBU to be annoyed with MIL? She has told DP that we need to reconsider our choices as they are only 'step family' and not blood. Well to us, their family, blood or not! My 'step' Dad who has raised me since I was 3 is my father and her 'step family' comments have really offended me
