<human>: Can you give me the gist of the text in a nutshell?

Ill keep it short and sweet: 

I moved to a new area last year and have recently started making friends with some women my age through a social group (this is HARD to do btw). 

One of the people in the group is a realtor, and while the entire group of us (about 5 people) have made jokes about how she will help us when we are looking to buy, there have never been any serious conversations about it..

That being said, I am looking to buy and may have found a place to purchase. However, my SO is from this area and we have decided to go with a family friend as the realtor. This is a non negotiable. 

I am trying to figure out how to share the news that I may be moving, and that I have gone with a family friend, to this group, particularly the realtor when I see them this week. While we never had any type of agreement, I do not want to offend or hurt anyone's feelings. I dont want to make this a big deal, but as these are relatively new friendships, I am still navigating how to discuss things without causing any problems.
<bot>: I have a new friend who performs a service as her job. I need the service but have decided to go with someone else. How do i explain/bring this up, without causing problems?
