Job -h always signed off as Me x, then stopped the x when he met ow and then started again with these last emails. I have always signed off - L x although did put Much Love L x on the last email. I do see your point though and will stop the sentiment.
Its habit - i put an x on the end of everything, emails, text etc to all my friends and it just happens naturally as i have alway done it with him. Will try refrain from doing it from now on - thats if he contacts me again needing a reply.
