He fell in love during lockdown

I fell in love before lockdown, we were discussing my moving to his city, how we would decorate our own place, what our wedding would be like, our future. During the second week of lockdown I started to struggle to get a hold of him, he messaged sporadically. I finally told him we needed to talk. We talked, he reassured me we were okay, he still wanted to be together. The last thing he ever said to me was “I’ll call you back in a bit.” 
He fell in love during lockdown. 
It just wasn’t with me.
