Yes it is difficult to do LL without interaction. However, if her LL is words of affirmation....you could have e-mailed "you looked great last time I saw you" instead of or with the I miss you e-mail. you see what i am getting at? My W has the same LL....I don't hold back at all anymore. If I think she looks good, i say it. i also try to encourage her in her business decisions which is something you can't do right now. Don't give up ...... try the words of affirmation.....go slowly....good luck.
