Issues

My boyfriend and I been dating two months now. We kinda did jump into the relationship. My ex an I were together basically my whole life. From when I was 12 all the way until I was 18. Than best friends/fuckbuddies until Oct of 2015. I am only 19. Than now my second boyfriend of my whole life. . Him an his ex ,I don't know much about his past. He never talks about it. But I do know apparently she cheated on him with his best friend. But I've been begging him to tell me how he feels about me. He denied a couple times due to his past he says.. so I respected that. But one day he came home quite earlier than most days. And he told me how he felt about me. Told me he loves me, but he's not in love with me. Which I completely understand. But he said he was still getting over a heartbreak. And honestly I think I still am too. I do talk to my ex some times. But just as friends nothing more and nothing less. But after my boyfriend told me how he truly felt. He's been acting really weird. I found one ear ring in the bathroom. I cleaned the bathroom two days before this. And no other girls come here. So I didn't think much about it. Just thought he lost one of his. Well I saw that he didn't. So I immediately went to the bathroom and I put the ear ring away. Than the next day I took it out and laid it on the bedside table. And then after that it went missing. And I didn't tell him about it. He won't let me go places with him not even to the gas station. He didn't cuddle me last night.. until like 5am. Than now he changed his lock screen. But he did get a call at one am from a random number.. is he cheating? Should I talk to him?
