SIL wants an invite for her partner to our wedding.
We are having a tiny wedding of just parents, siblings, siblings kids and if they have a serious partner.
There 19 guests.
There are four siblings who are unmarried.
My brother (27) : long time girlfriend of 5 years
My sister(30) : Single
BIL(30): In a relationship for 2 years
SIL(22): Newly dating
What we didn't want was partners who are likely to break up and we never see them again. So we decided unless they are the life partner we are not inviting. So we asked each of them to make this decision based on our request.
We asked my brother and he said yes his girlfriend is his life partner. They will probably get married in 3 years time. So she's invited. As his BIL's partner for same reason (hes older so the relationship is mature).
SIL had only been dating her partner for 4 months at the time we sent out save the dates, so the answer was no. SIL is also 22 years old so very young.
The wedding is next year and now SIL has been dating him for 1 year and is saying he is the man she's going to marry and want's him to come.
But the relationship to me is just not at the stage that would warrant an invite in my opinion. Partly due to age and maturity.
I met him once and he did feel younger than his age, got drunk and told us his childhood trauma. He admitted to cheating on his ex also.
This is her first love and she has fallen hard for him. She said they wouldn't marry for 5 more years as they're too young. But he is her person.
Now I don't know what to do. Invites haven't been officially sent out yet. Could I justify not inviting him or am I obligated to?
