Why does he get so jealous? 10 PTs?

There's this guy and he likes me because he told me and whenever I talk to other guys he gets jealous like he once asked what I was doing and I said texting and he asked who and I said him and other people. Then the next day he was like I'm going to bed hope you sleep well and I said well who am I gonna text now :( and he said if you get bored text your boyfriend and he knows I don't have one I think he was jealous I was talking to another guy?

But why does he get so jealous? Is he really into me and doesn't think I like him or something? help!

he really likes you and thought that you more like to text with another guy than him, i guess? it's cute tho to see a guy get jealous ^^
