It is highly understood that you would feel unmotivated, who wouldn't?
Yes, just be pleasant for now, until you get an appt with a counselor. Do ask if he/she are solution-based in their approach...otherwise you'll be there until the C's grandkids are in college, plus paying their tuition.
You want one that is "pro marriage".
I don't know if they would do it over the phone...they need to be able to "read" your expressions to specific questions that they ask.
Call around...see when you can get an appt. soon...
