There such a thing as the proper time and place for things.
For me, I shared with two women my past. One was a friend of a long time, another was a person I just felt comfortable with, also with abuse in her past.
I started the conversation in that direction when it felt right.
In your case, I would just stay in contact. I would feel gratitude for a caring friend as just that. Friends are hard to come by and quite valuable if you care for that word. You are probably quite treasured no matter what is shared right now.
I feel more like I do now than I did when I got here.
