a week is too soon in my opinion!
my bf met my family after 3 months and i haven't met his because they live in Germany but i will soon cuz they're coming soon!
i think u should wait a bit more!! =))

I agree with somebody who commented on the Facebook post thing, if his sister invited you, then it would be rude to decline, unless you said you felt it was too soon. Only you can really know. My boyfriend met my parents within a month (we both live away from home and they were visiting for the weekend and we ate in the restuarant he works in whilst he was working!) but I met his after four months, because they live in the UAE and visit very rarely. I didn't feel ready to meet them (especially since I was meeting all his cousins as well) but you have to at somepoint, and the sooner the better ideally, because if you make a good impression on the family, then you're well in!

I would find out if your boyfriend felt like it was too soon. Let him know you're okay with not going if he feels like it's too soon, but if he's okay with it, why should it be a problem?
I actually don't remember when I met my boyfriend's family, it just wasn't a big deal to either of us. Plus, it was about 3 years ago, haha. He has a very large family (he has four brothers and one sister, and all but one are married, and his sister has two children), so they're always having a party for someone's birthday, so I'm sure I met them within a month. If you don't make it a big deal, it won't be a big deal.

Honestly just go to the party and have fun. Have a good impression but have a good time. He would probably like that you want to meet his family. It is never too soon or too late. Its like you would meet your friends family. But the difference your together with him and that means you two are in it together. Enjoy it :]

I met him while travelling and we live 8 hours apart. After 3 days of travelling together we were friends and then we bumped into each other on some more travels 2 months later. Where we had a few DnMs, including talking about kids and he asked me to visit him. I had spent a total of 8 days with him. another month later I went to visit him, he lives with his family, I loved meeting them, he mum greeted me with a hug and a kiss and said welcome to the family... I spent a week with them.
The reason I went was because we are both very strongly family orientated. I guess it depends on how you feel about the situation, but if I was you I would go!
Good Luck

Probably too soon, but if his sister asked you too it may be pretty rude to not go. I mean it's reversed a lot, because thirty years ago you HAD to meet the family before dates. I guess it all depends on how comfortable you are with the guy.

I think a week is a bit soon too! I saw his family after about 2,5 months, he saw mine after 5 months or so:P If you think it's going too fast, you should just tell him, I'm sure he'll understand ;-) After all, it's only a week. You should spend time together with him a lot now, just the two of you.
Good luck!
