Do I really have to invite family to my and my boyfriend's civil ceremony?
Why don't you want your family there for such a special occasion?
I would rather it just be me and my boyfriend.
It's obviously entirely your decision who you invite to the ceremony. However, not inviting your family will probably make them feel hurt and upset. If you don't want them there for the ceremony, maybe you could have a party after it to celebrate with your family.
Family is just going to get in the way and they don't understand our relationship.
If your family isn't accepting of you and your boyfriend's relationship, then maybe it's for the best that they aren't there. It's likely they would feel uncomfortable and it may just make the ceremony difficult for the both of you.
