He says "I love you" randomly

But not very often the firt few months when I realized I loved him it was the hardest thing to admit because were not 'official' but close enough were together we don't talk to other people and he lives with me but he went to stay with his mom last night and we were on the phone and when we got off he said.."I really like you" and I played it off saying I really like you to and I love you just a tiny bit ..we laughed hung up. I'm not putting any pressure on him we've been together almost a year and he's not the type to lie about anything like that so when he does say it I feel like..its real...? But why would he just tell me he really liked me? Any advice helps :D thanks
