<human>: Give me a shortened version of the text

My SO (35M) and I (21F) have been together for 3 1/2 years. We have a four month old son together. The entire pregnancy he went back and forth about whether he was ready to move in together (for various reasons including: my age, the responsibility for me, his past, etc.), which was very stressful for me. 
We had finally settled on moving in together (I did not pressure him because I wanted him to be sure) and have been looking for a suitable location. 
However, now that we're actually looking at places, he's getting cold feet. He texted me on my way to work saying "I still think I don't want to move in with anybody." Followed by a text saying he didn't want to discuss it right then because he's taking a nap.
Now I'm stuck working a 9 hour shift with this bombshell weighing on my mind. I feel like our relationship is not moving forward at all and I don't know what to say to him when I see him next. And will he even care?
<bot>: My (21f) SO (35m) of nearly 4 years has changed his mind yet again about moving in together. Is this relationship even going anywhere anymore? We have a 4 month old son together.
