So I've decided I'm going to write my MIL a short note and include that in with the things I. Have to forward her. I'm going to do that, rather than just text or phone (I'm not sure I can deal with speaking to her at the moment, without getting upset).
Anyway, I was thinking of writing something along the lines of finding it easier for me (for the time being at least), not to hear, see or know anything about my H
I was going to add that of course, I would be very happy, as I always have been, to share a friendship with her.
