When love is young, it delights at the prospect of being missed by one's sweetheart. One wants to know how much one will be missed. The more, perhaps the better. One asks childishly "will you miss me?" and hopes the answer will be "A lot".
When love is secure, it dreads the prospect of being missed too much. One wants to be assured that the beloved won't pine and lose sleep and have heartache over missing one. One entreats sensibly "don't miss me too much, I'll be back soon" and hopes that the plea will be heeded.
