Friends with benefits or more?

I met this guy online through a dating site and we immediately clicked. We talked for awhile before we ever met because I was out of state for awhile. To tell you the truth, I think we rushed in the beginning because we were already saying “I love you” before we met. Finally we met, and things got heated pretty quick. We dated for a little but I ended up breaking up with him because I felt like I was the only one putting effort into the relationship. When I broke up with him he didn’t seem upset or sad, he actually agreed it was the best choice. Then a week later, he was texting me saying he didn’t like how we ended and he wanted to talk in person. We met up, talked and worked things out, and then got back together. Then I broke up with him again shortly after I found out he was texting several other girls and saying things that would imply cheating. From their on, we didn’t talk for awhile until we both agreed to be friends with benefits. He wanted it to be no strings attached so we never went to his house or mine and always kept it on the down low. What was usually every couple weeks that we saw each other turned out to be every single weekend. It would’ve been more if I had lived closer, but I lived an hour away. Then he wanted me to start staying the night again at his house where before he didn’t want that. Then he wanted to start going to the movies together. Then he wanted me to start staying the night. You see the pattern. Then one night he invited me over, and then said maybe we shouldn’t. I asked why and he said “the F-ing, gets old.” I didn’t understand that statement considering that is what we were and this is what he invited me over for. I ended up coming over and staying the night in the end. Then he invited me on a business dinner with his co-workers as his date. While we were on our way to dinner, he asked, “do you ever think about us?” I was confused and he added, “think about us being together one day. You know those couple who started off as just FWB and then end up getting married after a year or so of meeting other people and realizing we're meant for eachother.” I had no clue what to say because I couldn’t believe it. I started to share with him, later that night, about how I have been going out on other dates and he got seriously jealous. He said as soon as I meet someone else ‘he is out of here, at least that way.’ Whatever “that way” means. He would always glance over my phone to see what and who I was talking to. He just seemed to get extremely jealous. I thought FWB don't mind what else you are doing in your life. I can feel our hook up getting more pionate than it was before, just by his kiss and how he cuddles me afterward. Is he starting to get feelings for me?
