@Coley921,
It's difficult dating anyone who has a well-established social circle. The new romantic interest may stay outside of the pre-existing group for a long time.
My thinking on it is that I'm not interested in being part of that circle. My relationship is with one person, not the group. At the same time, I have to respect the connections in the group that existed before I came on the scene as a romantic partner.
Luckily/wisely, I always retained my own social circle and don't socialize only with my romantic partner/spouse. I continue to maintain my own personal life.
