How long do you typically wait to meet a significant others friends or family? ?

I really dont care if I ever meet any of them.

I’d wait about a month or two cause these days feelings change quickly and what not so best to be sure about the person instead of moving too quickly 

This is your 252nd answer.  It may depend upon external circumstances as well as the personalities and relationships involved. If your significant other has relatives in another country, for example, you may never meet them. Or, if you two are on a date and happen to stop by a parents' home for something, you might casually meet them without it even being planned.  No set rule or pattern exists. If you are getting tired of waiting and it suggests something negative to you, ask for what you want and see what the response will be. Should tell you  a lot. Keep in mind that because of Covid, human contact is being discouraged right now.

As a teen, pretty much that week, as you are children. In my 20's, it was a few weeks in. My husband's family was same day (mom), and a BIG holiday (dad and step-family). We had a lot of mutual friends, so that wasn't a surprise or anything. It varies. I don't think you can put a time limit, just whenever all parties are comfortable with meeting everyone. And not all families are created equal. On my end, I waited a good 3-4 months for my husband to meet my dad, because my dad can be a lot to handle sometimes, so I had to talk up my husband while talking down my father and pick a good time. And my mother insisted THAT WEEK to have family dinner, so...yeah. It can be a lot!

And it's not necessarily a huge red flag if anyone's SO doesn't want you to meet their family. They could have hang ups or simply not get along with them. I had an ex like this, he just despised his mother for good reason, so I actually never met her at all.
