I'm going to attempt to keep this brief but, the short story is, I'm fully against attend my father's upcoming wedding (relatively newly engaged).
Why?
My dad is marrying my husband's ex-wife. Whom he has a child with.
My dad is going to be simultaneously a step dad and step grandad to a child who refers to me as stepmum.
Its... too creepy for fcking words?
When they started seeing each other I made it clear to my dad I found it totally inappropriate and it makes me wince that my husband AND dad have shared a partner, but my dad called me immature and told.me to effectively get over myself. His wife has at least been a bit embarrassed about the whole thing but my dad completely maintains that this is just 'one of those things'.
AIBU or.is he a complete fucking nutjob?
(Just because I can imagine the questions about age, my dad had me young. He is late fifties, I'm mid thirties and my husband and his ex are late forties)
