Ideally, your close friends will feel comfortable with your partner and even form their own friendship with them.
But this takes time, and it's not uncommon for there to be a period of time where your partner is simply your partner, and not a fully integrated part of the friend group.
Unfortunately, this can create relationship tension and feelings of exclusion if it never shifts.

My best friend lost a parent a year and a half ago which led him to a mental health crisis. Our friend group has been picking up the pieces ever since. He's doing much better now that he's in therapy, but he's definitely gone through it.
