Oh, there is most certainly the potential that your growth from your work in therapy has an impact on the situation. My T told me long ago that my relationships with people will change. It may be met with a lot of resistance - and people can either be open to growing with you, accepting you for the changes and the effect it has on the relationship, or relationships end.

When I started therapy, I was married and had plenty of friends. Now, I'm divorced and have very few friends. The people worth keeping are still with me today - and the others, I learned were very unhealthy for me.
