controlling boyfriend

So im 19, about to be 20 in two months, and I've been dating this guy for 4 months and from the start we've been serious. I had a talk with him and told him i was looking for something solid and he said he was too. He's my age as well and im his first serious girlfriend. He's literally everything i wished and hoped for. He's handsome, tall, My mom loves him, he's sweet, etc. but theres one thing that's getting on my nerves 😒. He's soo jelous! Im not going to lie i like a little jealousy just because it makes me feel like he cares but today in the morning he went through my liked posts on Facebook and sent me a screenshot of my likes and reactions which was a mix of guys and girls posts but he's upset because im reacting/liking guys post. I would see why he would get mad if it was pictures of guys but its all funny memes that i like 😕. I really love this guy and i really think he's the one but i think he's over reacting with this .. advice please ? 😓
