John,
I thought you deserved to know, and perhaps Lydia has told you already, but I confessed my feelings to her. I thought she deserved to know the truth about how I feel for her.
Please know that I made it clear that I have no intentions of pursuing her. If she's happy with you, then I'm happy for her and I honestly wish the two of you only the best.
I hope all is well with both of you. Maybe we should meet some time, properly, and have lunch. If that would interest you at all.
Yours,
Peter Hale
