What do i do about this guy i am seeing?

I was introduced to this guy by my best friend back in september 2010, i was living in washington at the time so it was just over the phone. I moved to colorado and we kept in contact, i went to see him in person in wyoming and we could not keep our hands off each other. I ended up moving up to wyoming to live with my best friend. We started hanging out all the time and he wanted my kids to hang out too so they did. We had so much fun together it was good. But then he changed and started acting different. I had to call and intiate everything, once in awhile he would. Now we are going on 7 months and i asked him what we were doing and i wanted to be exclusive . And that if he didn't want to be than we need to just say we are friends and move on. He never said anything he avoided the questions and text messages. He said he likes spending time with me. I told him I was falling in love with him and if he didn't feel the same way we need to change things . I told him to be honest i can handle it and would respect him more. If he wanted to see other people great let me know so i know where i stand. He just stared and said nothing then changed the subject. We had a miscarriage two weeks ago. It has been a rollacoaster with emotions and loss on my part. I know he is sad but he acts like it never happened. We recently had sex he intiated it but he would not touch me to please me. I was losing my excitement for it right in the middle of it and i had to grab his hands a have him touch me. I felt so unattractive. We than went to a movie and we had fun until we were seating in our seats and he joking around then he was acting like he was going to spit water on me and i said you would not to that, that would be rude. And he did , he spit water in my face and all over my dress. I was humiliated and embrassed and wanted to cry. He say that hurt me and said take a joke. He has never been so rude to me. I didn't know what to do. He hardly response to my text anymore . I feel like i have to ask all the time to spend time together. Im so confused and sad. I dont get him. If i dont answer his texts or calls i get drilled or threatend with i guess im not for you and have a good life , until i text back. Help me please, i feel lost , i don't know what im doing anymore.
