100% would need forever. I don't think things work this way, at least not for me. You are making him suspicious, by the way, by doing this. If you have a story, he will eventually know it. Meeting family tells a lot about the person, especially in large cities where tracking people history isn't easy. Even if your relationship is not good with your family for any reason, I think he needs to know why, like if they are mean and bad people and alcoholic .... etc.

It seems to me that you two have different views of the relationship; he seems to want to take it to the next level, but you are not. I think you need to talk about this. I know you like to hear people support you, but him meeting your family isn't a compromise, it is a part of an evolving relationship.
