Just like I told JCJ NO ASSUMING!!! You don't know what is going on there and you do not want to assume the worse. Today is NOT the make it or break it day so get that negative thought out of your head.
You have to fill your head with all the positives and act 'as-if' this is going to be a pleasant conversation of just making a schedule. Do not act defensive and just validate that you will need time apart here & there and are willing to come up with a schedule (together) that you both can agree on!!
