Do guys think he’s only traveling states away to see me just to have sex with me?

I met this guy on instagram and we’ve been talking for 2 months. He wants me to see him so bad that even offered to pay half of my trip but I declined. Now he’s willing to come to my state just to see me. I feel he only wants sex even though I was the one starting the sexual conversation just to end this fast.
• He talks to me on the phone almost everyday day sometimes twice morning and night.
• He tells me about his day and show me where he works through FaceTime.
• we already had couple of arguments over his jealousy but he ends up acting normal again (to me that’s fake jealousy).
•he talks about having me as a wife but told me he needs to know me first.
I’m a person who’s always thinking negative and won’t believe a thing because my ex husband is extremely faithful so I don’t think I can get something like that.
