I want to make my boyfriend come with me on a three week trip to Europe.
Why are you making him?
To force him to like Europe. So that he can learn European culture. He keep saying it's shit, but I think it's nice.
You need to have him agree before making him go. You can't force him to go if he doesn't want to.
It's my gift to him and I don't care if he doesn't like it.
Your boyfriend is going to think you don't respect him if you're forcing him to go somewhere. It might cause strain in your relationship. Maybe you can watch some European movies or shows with him first to get him to appreciate the culture?
