Feeling lost and alone

I met this wonderful guy back in July. We went out a week and then he gave up because he wasn’t ready for a relationship. I was hurt of course, but I moved on. Fast forward to end of January he messages me and says he wants to try again. Me being the nice guy I am gives him a second chance. For the next month everything went well and then bam this past weekend something bad happened. Normally we see each other every week however this weekend he decides he doesn’t want to because he is “stressed out due to work”. I have trust issues, so I don’t buy it and see it as a lame excuse to back out. I do think he’ s trying to give up on me again. So of course I let my anger out and I think I scared him off. I don’t know what’s going to happen. I haven’t heard from him since sunday night and am starting to worry that it’s over.
