Long distance worries

So I started going out with this guy a couple months ago when I went out of the country to visit my dad after my parents separation. He's a family friend so he's very close to my cousins. So we decided we liked each other enough to date. Now I'm back home in the US and he's away at college in France and I trust and know he won't cheat but I can't help but worry it won't end well because of the distance and the opportunity for any girl to convince him to cheat on me. But I do love him and I hope it'll work out, idk what do you guys think ?
