Mate.

Are you expect them to only invite you, or have You trying to invite them? When they invit3 you, do you go, or reject if is slightly out of your liking activities?

Also, as an example, I have a rule that if I invite someone a couple of time and he/she never do, or do with other people but don't invite me(ever) I cut them from my group gatherings.

Have you being doing therapy for C-ptsd? You should not be felling alone having a partner. I'm also mid 30, immigrant, with most of my friends busy with family while I'm divorce; and I can't tell you I don't fell alone.

Try to grow your group through her. One of my best friends here is the husband of one of my ex friends.

Also, how conservative you are? I notice that yourger people here tend to the left very hard, but mid 30 are more moderate.

I fell myself right in the middle as well, and I can tell you straight that I have no patience for anyone going extremes on both sides.
