Does he want to be with me?

So, my situation is a little complicated.
I was dating a guy for about 6 weeks. It developed quite quickly; we only actually dated for about 3 weeks before we started staying over eachothers houses as we live a good 30 miles apart and it's just easier. 2 weeks ago, over the weekend I hadn't heard anything from him for a few days but I didn't worry because we don't text that much anyway. But on the Sunday morning I got a text from him saying sorry for not talking, but he's been upset because his ex got in touch to let him know her mother had passed away. I admit, I did freak out a little (to myself) that he had been in touch with her but I tried not to let it show and I was completely empathetic and understanding as to why he was upset. On the Monday we talked a little over text and then he decided to drive to mine and stay with me for the night; we had a lovely night together but he did seem a little distant. On the Wednesday night, he text me and told me he wanted to slow things down and go back to dating, obviously I was upset but I agreed because if he needed space then I didn't want to push it. Later that evening he text me again asking me not to go over the next day (like we had planned) but I had already bought my train tickets so we stuck to the plan. So the next evening I went to his and again had a lovely night. He left the house early on the Friday morning as he had work so I went home around 9am. He was texting me while he was in work and I joked around saying that I was going to stay at his for another night; he text back saying that it was all getting too much for him. I called him immediately and asked what he had meant; he said he couldn't handle me staying over another night and wanted to break up. I calmly explained that I was just joking and that I was actually at home, so he just apologised and said forget it. But I got annoyed when I realised that he wanted to break up with me over something so small, so we did end up breaking up over the phone but I said I that I wanted to see him so we could talk about it properly. I went back to his again that evening and he explained to me that his ex had made him feel guilty for being in another relationship only six months after they broke up. But he also told me that he was falling in love with me and he felt guilty for that too. I understood that completely so I decided to give him a week to think about it. The hindrance to that week was when I realised I had missed my period. I took a test and saw a very faint line. I didn't want to tell him until the next week in order for him to gather his thoughts but I felt too guilty for keeping it to myself so I called and told him. Obviously, he freaked out big time. We agreed that I would go to his the next Friday to take another test. All week he had been texting me to see how I am etc. on the Friday, I went to his, took a test and it was negative. We did a few more through the night and they were all negative. What confused me though, is that regardless of everything that's happened, he still acted like a boyfriend to me. He kissed me, cuddled me etc. and before I left his on the Saturday morning he acted so natural and just said he'd let me know what his shifts are so we could see eachother again on the weekend. I'm so utterly confused as to what's going on right now!
