What is going through his mind?

OK, I'm 26 and I recently met this guy about a month and a half ago. I was introduced to him because he is going back to college and needed some help proofreading his English papers. It started out that he would drop his papers off to my mom's office and then I'd pick them up, proofread, and return them to her to give back to him. Well, he got my number from my mother and called one afternoon to thank me for my help. He started texting me and calling me every day just to chat. After his second paper, he text me and asked if he could take me out to dinner as a thank for my help. I said sure and we went out that Wednesday (the restaurant he chose is a very popular date place). We had a great time just talking and laughing. We left the restaurant and got back to his car, and I thought he was going to open the door for me but he kissed me. And that turned into a little make out session, which was repeated in the driveway of my house when he dropped me off. He texted and called me the next where I told him that I need to explain something to him. I had been dating a guy for a short time before he left on a business trip for six months (we put things on hold and said we would see how we felt about each other when he came back), but I wanted to tell him instead of not mention it at all. He told me that he had been seeing a girl as well, for about a year. She wants to move in with him but he keeps turning her down, and for right now things were ok but he knew she'd bring it up again and when he puts his foot down about it, he doesn't know if it will last. A few days later I went over to his house to help him with a paper and we ended up making out again and having sex. He still calls and texts me throughout every day, except on the weekends when this girl comes out to visit. He said he can't talk to me then because she gets jealous and goes through his phone and everything, but when she leaves he will call or text me that night. I'm still helping him with his English work, but I was wondering how anyone else viewed what was going on? What is possibly going through his head? What do I do? etc.
