Where is the line?

I let her initiate and dictate contact during the match. I wanted to be sure she didn't feel pressured by my reaching out. When I wanted an update and hadn't heard from her, I contacted the agency. After a bit of weekly contact, LO's bmom decided she was getting too close to us and needed space. We went for several months just getting updates from the agency.My personal opinion is that it's best to let the emom dictate contact.
