Portia - one thing that I have learned with MLCers is to see if there is what I call 'follow through' They do have moments of clarity, and say this stuff, but the important thing is What are they going to do about it.

So the straight answer (for me) to the miss you/love you is simply "hmmmmm so what are you going to do about it?"

if it MLC they have seldom thought this far!! If they are genuinely feeling for where you are it poses a very clear question. And a big hint that something might be expected!
