"Friends of the ex/mutual friends" etiquette
Alright, so I moved to the city my ex lives in a week ago. I don't know anybody here except for him (but we're on NC) and his friends. I've only ever met them with him when I visited him here, but I like them and they liked me and we have each other on Facebook.
Now my question is, they are the only people I know here, and I do feel a little alone. I am NOT contacting any of them of my own accord because I don't want to put them in a weird position, but three of them have now written to me and I've already met up with one of them and am talking about it with the others. Again, I always made sure they initiated it, not me. But I feel that there is potential for real friendships with them and I'm very happy to know people in this city that I already have some sort of a foundation with, and maybe I could also meet their friends and so on.
But of course the issue here is that they are originally my ex's friends, and him and I are on NC. He knows I met with one of his friends (his best friend, who is also new here and was happy to sort of know someone else), and my ex was OK with it but a little uncomfortable, which is understandable.
So what is the right thing to do here? I don't want to be a jerk, and I'm afraid I might qualify as one if I keep doing this. But on the other hand, I really would be very grateful to have the opportunity to know somebody, and I make very sure that it is their idea to meet me and I'm not putting them in a weird situation they don't want to be in. And of course it goes without saying that if he's invited by them, I won't go to the event and make things awkward, and I won't discuss the relationship with his friends.
Thoughts?
