"...the only reason I signed "With Love" is because I had signed a previous email "love" (as per my DB coach) and my H responded positively to that email."
Certainly, if this is floatin' things along, it's the 'modus operandi' (mode of operation) then go with it. This whole thing is about watching and taking note. If it works, especially if it's consistent don't screw with it.
"If I had wrote that in Sept, he would have flipped out but I think because I act as if a D is inevitable he is okay with me using the word love as friends."
Sounds like things have moved up another level here, awesome. Patience though. Make sure it's genuine and solid before smothering H with, 'you're my forever ever more' and really deep stuff like that. Don't forget to keep chippin' away at the good changes too. Even after reconciling.
I haven't posted much in the last seven years. I've been a lurker. Just lookin' to put back all the good help I've gotten...
