Should I break up with him?

[Yakiniku]

I'm not so experienced with dating and relationships yet. This is only my second one and the first one lasted a week.

When I first met my current boyfriend we were extremely attracted to each other mainly because of our looks. We hung out with a group of friends several times and he eventually asked me out. I'm my opinion the first date was extremely uncomfortable and I thought it was awkward but he was so sweet and happy so I let that feeling slide.

Right after friends found out we were dating I got really embarrassed and I hardly talked to him when we were with other friends. And I hate how lovey dovey he is. He constantly tells me how cute I am and he really likes me and first I thought I was just embarrassed about and and thought it was really cute of him. but I could never get myself to say "i like you" back to him >< even by Facebook!

Now I've moved back to my hometown in japan for 1 year but he really wanted to do long distance so I agreed. But our conversations on Facebook don't continue and Im not having fun talking to him. I hate how I don't feel like I'm his friend any more because he constantly brings up topics that reminds me that we are dating and he likes me a lot and I'm beautiful.

When he says those things I get really uncomfortable. But when we don't talk for more than a day online I miss him a lot. He's originally from japan and he came to Canada as an exchange program and was going to stay 1 year but because he likes me he begged his parents to let him stay until graduation. so staying 2 years.
We even planned to meet in Japan during winter break when he goes back to visit his family. I'm happy about meeting him again though but wouldn't you feel like that with any friend?

I just feel like he's constantly pressing for me to say "I like you or love you" he actually kept begging me to say it onetime. and is it normal to think other guys are good looking while you are dating someone? Also these days I can't help but think how we only have like 2 inches height difference or less. I'm 5'6 and he's a bit more on the lean side. I've always liked guys who are tall and manly looking. and I keep thinking how unmanly he looks
my type is often manly and does sports. I tried to look past his looks but our online conversations aren't helping. and I hate Skype >< so we haven't video chatted or anything!

I'm having thoughts of breaking up with him because I'm no longer sexually attracted to him. and I always thought that having a relationship with someone would be like me talking with my best friends like us having endless fun conversations and being able to be goofy and hyper around him.
