I believe maylie meant to say, it is NOT an accident. and I don't think it is!! This is wonderful! Your landlady sounds like an awesome lady, and there is a reason you ran into her with the guy, and she reached out to you to ask about him, and when you told her, she just happens to have been in al-anon for 7 years (ah!!! so awesome!!) There are no coincidences! Your higher power is beckoning you to take the next step in your recovery!!!
I read something once that I really liked, "Coincidence is God's way of remaining anonymous". To me, your experience seems like a great example of that
go!!!! I've only been to a few al-anon meetings so far but they have been immensely helpful to me.
