Has he lost interest in me?

I (30 years old) have been dating my 40 year old boyfriend for 7 months now. For the last 2 months I have been staying at his place, practically living together. He has been avoidant in making the decision of whether we should officially move in together, so I suggested we take a week apart to miss each other and think, he agreed. 4 days passed by, we haven't seen each other and he hasn't called/texted and I ran into him by accident today. He hugged, and kissed me, held my hand, we went for lunch and he genuinely looked like he missed me. Then he walked me to work and told me twice "see you soon"... I am confused, seeing as tomorrow is a Friday and technically a week, shouldn't he have made plans with me? What is all of this supposed to mean? I have my things at his place, and a key to his home.

Has he lost interest in me?
