How do I choose between the two men I love?

I was in a relationship with a guy for over 3 years, we broke up because I wasn't sure about the relationship. Then I met this guy from Saudi Arabia, who I have been with for over 6 months now. I love both of them deeply, but in a different way. My ex was the perfect guy, I mean literally if I had a check list he would be classified as a saint. He is in the military and I just wasn't sure if he was "the one." See I feel like I can't tell him things, like about the past. Only because he thinks everything is bad so I feel like the devil for some things like smoking while stressed. Anyways, the guy I'm with now is amazing, he is so sweet and I just love him to pieces. The thing is my ex wants me to come back and marry him and move away. While my boyfriend was going to have to go out of state for school, but now he is staying for 2-3 years. Were not very serious, he tells me he really likes me and cares about me all the time. At first he said he couldn't get serious because his religion, he is a muslim. He tells his American mother about me, but doesn't tell his dad because he isn't allowed to date. Yes we have sex, which is wrong, but we do it anyways. He recently asked me to move in with him( I have stayed the night with him every night for 5 months) but now he wants us to share a house, but have separate rooms for looks and for our stuff ya know? All of his friends know about me and like me, but some people think he is just in it for the sex, which I highly doubt. He is kinda really jealous, like if I don't answer my phone he'll call and text a lot getting really mad, or come to my house. He has mentioned that he wants me to be a muslim, I think because he cares. Another thing, when we were together about a month I got pregnant, and he automatically stated that he wanted me to have an abortion because his dad and his family would be outraged and disrespected, see were both in college, he is getting money to go to school. So I decided not to ruin our futures and got the abortion, he paid for it and was there taking care of me the whole time, he felt really bad, we were both upset. So now I don't know if I should move in with him, not knowing if we even have a future together, or get back with my ex and get married and move away. Please give me some advice.
