Does he still feel anything for me?

My ex and I have been split up for about 6 or so months now. We have been in contact here and there. Once, about a month and a half after we split up, because our mutual friend and former roommate got into a really bad accident and passed away. We talked for about 2 weeks and then I told him I didn't think I could be strung along anymore. The second time, we reconnected through a friend. This was about 4 months post breakup. I stayed with him for two weeks and we talked about working towards being together and then one day he decided he just wanted to stay friends. I hadn't really heard too much from him until about a week ago, which was about 6 months post break up and he was asking for the necklace that our friend had made him a while before he passed away. At this point, I was dating someone new. I had only been with the guy for about a week, but he already knew about it because he was in contact with my new boyfriends ex girlfriend. He immediately wanted to meet up and exchange the things we had left with one another.

This part gets odd and tricky for me. He comes to my house, comes up to my door, gives me my things and I in turn give him his. We don't say anything to each other and I shut the door. I waited until he had pulled out of the driveway and was down the road and went outside to smoke a cigarette. The next thing I know, here he comes up the road again and into my driveway. He walks up to the porch and apologizes for "being rude" and asks me how I'm doing. He also mentions how he likes my hair and thinks it looks cute on me. He asked me a lot of questions and I didn't really ask him anything. Just answered his questions and remained silent. We talked for a little bit and then he said he had to go. On his way to his car, he said "I don't wanna be here when your new boyfriend shows up." Which, I didn't expect him to say. He's usually not that confrontational. But it happened.

Me and the guy I was with aren't together now. It didn't last but maybe a week and a half with us and we just weren't feeling like things were working out. I miss my ex and I'm a little stuck on him. He was my first love and we were together for about 4 years. He's the only relationship I've ever had and I don't know what to think about recent events. Does he still feel anything for me? Does he still care? It's all just a big ol mess and I wish we could just work it out and get back together.
