Search Results: meeting a guy online

So because times have change and online dating has become very popular, sometimes meeting a person skips certain steps.
So here is the scenario: Let’s say I met this guy online, when out with him on a couple of dates (dinner once and to see a movie another time) the other times have just been a chill evening at his or my place. Over all we’ve hooked maybe once or twice. Nothing has been said wether we are officially dating or not. We text a fair amount, but no real connection besides “hey you free, wanna hangout?” Or “whats up how was your day?”. Since nothing has been said of what this is, I’ll assume and keep dating other people, however the guy in the other end isn’t seeing anyone else. Does this mean he thinks I’m his girlfriend or that we are dating?
Because if he does it would mean I’m cheating or that I would have to end things. And in the other hand if he doesn’t think we are together will I still have to tell him that I’m seeing someone else?

I have made multiple multiple questions about this situation and I just want to put a final end on getting peoples opinions opinions on it. It will really help me.
- I have known this laid back guy for 1.5 years we met online
- at the beginning things were good, we were flirting/ making sexual jokes (I went along with it)
- I was hesitant to meet him because I thought he wanted sex, I lead him on for awhile when it came to meeting up
- he gave me multiple chances with giving things a try
- we have argued a lot through out
- on our first date, he paid, it was quiet, got to know him a bit, made out with him. After our first date his answers on how it went was vague.
- after our first date shortly after I found out he hooked up with a girl, he told me he thought I wasn't serious.
- he asked me randomly to be his girlfriend in the summer time and we kind of left it.
- we tried to give things a go and then I got cold feet.
- when we weren't talking and i was going out with a guy he messaged me asking how my "bf" was
- we talked a lot about our past and how he told me he wanted to be with me and that he liked me. I told him the same. He told me a couple times he wanted to move on but I wanted him to give me one last chance. Anyways we went on our second date, I paid, got no thank you. We had nothing in common. We did make things official before our second date. After our second date he said it was fun, but he felt nothing.. ( he did told me he was in the mood during our date) He then told me after that we just went on 2 dates, that I was weird etc..
