He doesn't think we will work out, do I give up?

I recently went on a date with a guy and we both thought it was an amazing first date. Hence there was date two and three which was a little spaced out because of his busy schedule and some unavoidable circumstances on my end too. But then i began to overthink things (that time of the month came, and i got emotional) and by date 4 that's what he told me. He said he doesn't think we will work out because he thinks we're going to get into a lot of arguments just due to the fact that his job takes a lot of his time and he might not be able to handle my emotional outbursts, which i told him only happens because i couldn't be sure he actually liked me yet. He told me he liked me and he asked me if i would be okay with his busy schedule. Initially i thought he had already made up his mind about us and i responded, well if you've already decided, then there isn't really much i can do. we stayed a while longer and had a bit of chat, and he just wanted a response from me to make sure he was making the right decision. he kept asking me, what do i like about him, he asked me if i agreed with what he was saying to me, he told me what he liked about me, and i started to sense that he hadn't actually made up his mind. So i asked him if he was telling me what he told me today so that we could work it out or was he just telling me because he hoped i would accept it and leave it alone. he said it was option 1. so i responded, what if i told you that you being busy at work wouldn't bother me? he said then he'd have to think again. and asked me if i was willing to wait a few months for his schedule to clear up a bit? and to that i responded, do you want me to wait? and he said he doesn't think it would be fair to make me wait. We left it at that because something came up, and we haven't contacted for a few days. What do you think? Is he thinking about it? or has he already decided? (i just don't want to be waiting for a response that might never come because i'm too blinded to see)
