Did I scare him off?

Me

I was with my now ex for about 4 months. We both were busy. Him with two full time jobs and me in nursing school and working full time. The other week I finally had a weekend I didn’t have to work and I was excited because I thought he and I were going get to see each other. Things didn’t work out that way because he said he had some things he needed to do. I was really upset because the week before he said we’d be able to see each other. I also was very upset because I don’t get to hang out or talk to people often unless it pertains to work or school. I’ve been really lonely and I was telling him about this. He then says he feels like he wants to take a break in our relationship since he feels like he doesn’t always have time for me. We FaceTimed the other day and he said he still wanted us to see each other and talk. I text him Tuesday but other than that I haven’t heard from him at all
