I don't know anymore..

So I met this guy (let's call him Jack) about 8 months ago. He's French, but he knows a little English. It's quite unbelievable, but our connection with each other grew each day we talked. Only a month ago did we admit our feelings to each other. It's difficult because recently I've started to feel like there's nothing left to talk about? He's a real sweetheart and I absolutely adore him, but I feel like he's found someone else even though we hadn't made it 'official' yet. I'm beginning to think that he's getting bored of me, and doesn't really want to talk as often. I dont know, any advice?

Thank you xx
