Time to end it?

My boyfriend and I have been together for 4 years and I've never once thought about ending things until now. I recently went on a camping trip with a friend of mine and the entire week I was gone I didn't hear from him at all. When I got back the first thing he said to me was that he wanted to have I miss you sex, not that he missed me and wanted to see me, he just wanted sex. This started a major argument because for the past few months that seemed to be the only thing he was interested in. After we got everything talked out he told me that while I was away he got into a car accident, got a new car and got a new job. Then he told me that because of this new job he needed to go out of town for 3 weeks for training and he said he had no intention of telling me about this trip because he wanted to see if I would notice that he was gone and the only reason he was telling me was because his mom yelled at him. This has opened my eyes to a number of red flags that I had ignored in the past, ie: only visiting me for sex, asking if he can get a sugar momma, telling me that if we ever had kids he wanted a paternity test, telling me that he would only watch my favorite movie with me if I gave him head throughout it. Do y'all think that these are problems that can be worked through or would it be for the best to end things and move on?

**UPDATE**

So I did end up breaking up with him about a year ago. It actually ended really well and he and I are still friends, we ended up just wanting different things. He and I have both moved on, I'm now with a guy that I've been pining after for 12 years and he found a wonderful girl that wants all the same things as him. Thank you all for the advice and the kind words.
