Long Distance Relationship Vs. Work Friends?

I just moved to LA, where I have tons of new work friends asking me to go clubbing or drinking ALL the time. The thing is, I was never really a part of the club scene in college, and I’m also engaged to a wonderful man who lives in Boston, where we went to college together.
My friends know I’m in a long-term serious relationship, but NONE of them are in relationships as serious as mine, so I think they don’t really understand– in fact they mostly just have short hookups or date multiple people. I’m totally fine with their choices, but we’re all the same age (23-25) and I don’t want to look like the old lady. I admit that I never told my new buds I was engaged- it always seemed really out of place to tell them.
I don’t really enjoy drinking– it’s too expensive and I only really like to go to bars when my fiance is also there. I definitely don’t like clubbing, especially when I’m there and appear to be a single girl. I’d much rather go to coffee shops or art museums or performances, or stay in and cook or watch sports.
How do I turn down my friends’ invites to go out clubbing and drinking? It seems like their only mode of hanging out, ever. Most days after work I just want to go back to my apartment and talk to my fiance on Skype. But I see these friends at work ALL the time– they really are my only friends here, and I want to hang out with them without being a bummer on the party. I don’t want to be the girl that everyone thinks is boring or never gets invited to hang out… Heaven knows I’m already feeling lonely enough being long distance with my fiance. What should I do?

What Are The General Rules In A Long Distance Relationship?

I am engaged but right now i am in a long distance relationship (4 hour flight) (two different culture/countries; USA & SKorea). Just became long distance relationship when her visa expired this September. I trust my fiance but since I don’t know much of her old high school/college friends (I only visited Korea once), I get worried when she goes out with them to drink. Especially that the high school friends WERE her drinking buddies when they where young and getting drunk. I like to know what are the general rules for this situation. What are the “DONT’S” in this relationship? Can she still go out with them? Until what time can she go out? Who can she go out with? What are the things she & I CANNOT do anymore when we are engaged? What are the rules? Help me out. I don’t like to control her.

College/high School Relationships? It’s Not Long Distance, But I’m Worried Just About How It Keep It Strong.

My boyfriend is staying in town for college and commuting and I’m a senior in high school. We’re pretty serious and we trust each other. I’m just not sure about the different environments and settings and people we’ll be encountering and how it will affect our relationship. College friends, classes, etc… I just am so worried we’ll drift apart, and just want to ideas/advice on how to keep things going strong. I know it’s not the typical long-distance thing, which I think gives us a better survival chance. It’s still tricky all the same. Any advice or success stories would be greatly appreciated!
