I'm dating a 23 year old

I've been trying not to write this post, but the time has come. I will be 33 years old in 2 weeks. I have been dating my boyfriend for the past 3 months, almost 4 now. While I am the happiest I have been in quite some time, we are ten years apart and that is beginning to show itself more and more.

My boyfriend is still in party mode. He likes to go out to bars or parties on a regular basis and get drunk. I never hit this phase. Yes, I have been drunk before and I enjoy having a drink or two here and there. However, I do not like to get drunk and I'm thinking now is not the time to begin developing that habit. (I missed that stage somehow. I also missed out on the drug scene. I think I was shown one too many of those ABC After School Specials.)

Case in point, it is Saturday night and we are leaving for Europe on Monday. My boyfriend has a lovely habit of springing surprises on me like, "I'm going to party in Sacramento tonight, I'll be home sometime tomorrow." Whoa tiger... My response was , "WTF? When did you plan to do this? And better yet, when were you planning to tell me?" (He brought this up at 2 PM today after ditching me and our plans to go out last night.) It's not that I really care about him wanting to have fun with his friends and I am not in the same party mode for sure. My issue was him going to hang out with 20-40 gay men in Sacramento where drinking and partying were sure to be happening. I trust my boyfriend 100%, but I don't trust the other members of my tribe. (Note My boyfriend also informed me two nights ago that two of my friends slipped him their respective numbers and said, "Call me when Mark isn't around.") Also my boyfriend does not drive or have a car, so he was going to be dependent on friends of ours to drive him home. I feel like one should always have the ability to leave a situation if need be and Sacramento is an hour and a half to two hours driving time from our apartment.

I gave my boyfriend 2 options. Either bring me with him or don't go at all. My boyfriend was like, "You can't give me ultimatums like that." Uh, yeah, I think I can. So now my boyfriend is moping around the house and not speaking to me. Am I wrong on this one? If you're dating someone, don't you have the right to veto certain situations that you deem to be a train wreck waiting to happen?

Hope everyone has a great weekend. Cuidate.
