Wedding invites

Hi girls I’m planning on sending my wedding invites out soon however I have a few questions which I’m curious on.

When I invite my work friends do I also invite their partners and all their children even though I have never met them or do I just invite my work friends?

At work there’s only 15 of us however I only really get along with about 13 of them and would class them as my friends but not 2 of them, do I just invite my friends or should I also include the 2 whom I don’t get along with (they have made it known that they don’t really like me)

I just don’t want to be rude! Please give me some advice x
