Long story short, my fiancée and I wanted a small wedding. As small as 5 people max, signing the papers and eating at home. There are 34 guests invited now, eating at a restaurant at a cost of 165€ (about 200$) per person, suit, dress and honeymoon apart.
We decided to invite friends, parents, siblings + children in my case, friends, parents, godparents + children in hers.
We both have difficult relationships with our families. Bad experiences, distance, lack of contact, support, respect, etc, which made us decide to cut the invitations there. No uncles/aunts, no grandparents, no cousins.
After telling my father his mother and sister wouldn't come, he was pissed, but accepted my will, and yet he told me I should call her to let her know, which I didn't find right at that time, and I don't find it right yet. Similar situation was told to my fiancée.
Two weeks ago, we called everybody we didn't invite but our parents felt important to know. Just to avoid shafting them.
I've also had calls of other people that had a better relationship with people I didn't invite, telling me I should send them an invitation asap.
Now, it's exactly 8 days till the wedding. I got a message from my father telling me that it's my wedding, but he feels I must invite that branch of the family anyway, because it's just 2 more people. The lists are closed, the menus settled, and my fiancées side wouldn't get to come in time. It's totally unfair for her, and I've spoken to her about this before.
This is a stressful moment for me. I had to fight the list with my girlfriend (I have a really large close family while she's an only child), and this was the best balance for both of us. I told her about this and she freaked out she couldn't invite her family but I would be able to.
How can I push my father's decision back?
