Does this guy just want me for sex... or should I move on?

I met this guy 3 months ago. Our first date went really well and on our second date one thing led to another and we had sex. He had previously told me how he travels a lot for work and that he would be in NY for 2 weeks practically every month. Since he would be leaving soon and we moved too fast I thought he would probably end things, but he didn't instead he text me a day later with "you are the best" and after that he began texting me practically every day, and yeah some were sex texts, 2 weeks later he came home but it wasn't until another week when we saw each other, and yeah we fooled around a lot. He continued to text me, and 2 days before he left he text me "I am so sorry but with my schedule being so crazy, I simply don't know how to find the time for us to hang out. You are a great girl and I hate being mia all the time so I would totally understand if you want to see somebody else. I am really sorry but I'll be slammed for the next few months with work” I was bummed and thought he was just letting me down easy. I didn’t text back, so he text the next day “how are ya” I called him and he kind of urged me to date other people cause he felt he was being unfair to me and then said he'd keep in touch. Our conversation led me to believe it was over and I was disappointed. I didn't hear from him, So decided to move on, started dating another guy who is okay, then I get a text "in NY thinking about you, how are you?" I did not expect to hear from him, and I was a little excited to hear from him, so I text him back found out he was coming home soon, he text me the next few days and was eager to see me so we met up and he just confused me more, we made out a lot, but he was a little awkward and stand offish at times. I asked him if he likes me so much why does he want me to date other guys, but he just replied how he wants to be fair, we went our separate ways, but I was feeling he only likes making out with me. We had sex once, oral sex twice, and we have made out a lot. After our last meet up I felt he may be just using me, but now he has been texting me a lot like every other day with “hope your having a good day, I am thinking about you” he also text me about how beautiful I am and how much he really likes me, and wants to see me more when things calm down at work. I was frustrated one night after receiving his text, so I text him “I have been thinking and I feel this isn’t going to work out” he text back “Why? I like you a lot and I think you are beautiful and I am really into you” I didn’t text back until a day later and told him how I am frustrated, which he replied how he really likes me and thinks about me all the time. Do I end things with him? He also says his busy schedule should calm down after October and hopes we can hang out more then. Should I wait and see how things go? Do I keep dating other guys, but I will end it if I find someone I like more.

Okay so he has been gone for two weeks and texting me at least 1-3 times a week with "hope you are having a good day... I am thinking about you" or " I am missing you" This Saturday he text me "I am flying back tonight... I really want to see you soon"

Now I have to tell you he has been quite the last minute date guy, calling me late, wanting to see me in 30 mins. and I have had to turn him down because I was busy ... I let him know that he needs to plan dates further in advance.
