Music Connected Us

Recently, I passed an audition to perform at a dance. He was a performer too.
As my song would sound best with a LIVE band, I was introduced to him by the organiser of the dance.
He agreed to get him and his band to help me, before he knew me.
What a nice person.

I ran him to him a lot, before formally knowing him.
Then one day, I was waiting within the building he lives in, as I was waiting for a friend there.
He was coming in, but was looking for his key for a long time.
I opened the door for him, and realised it was him.
Then we couldn't pretend not to recognise each other anymore.
He said "Hi, see you next week [for our practice]!" and ran away.

I thought he disliked me, as he didn't talk to me about anything personal online (before we met)
and he didn't even stop to chat. Just ran away.

Soon, we were organising our 1st practice. He wrote details of the location, time of practice
and he asked me to call him. I could answer him online, and besides he has my phone number..
so I don't know why he wanted me to call him.
When I did, he seemed nervous as he talked almost non-stop (about details of the practice).

When we finally met to practice, everything seemed like heaven, like perfection.
He was extremely friendly, much to my surprise..not cold at all.
Just a laid-back, open, kind, talented kinda person.

So after our performance at the dance...
and some pics were uploaded, he mentioned that we look like siblings in a pic.
He then asked me if he could crop me out of the pic to make it his profile pic.
He said his gf would be angry otherwise.

Then, I realised he has a gf. We started chatting about more personal stuff, and seemed like he opened up to me. I also opened up more, became somehow more relaxed when I knew he has a gf.

He said a girl hated him for cropping her out without telling her..
and I said maybe she thinks u don't think she's hot.
Then he said he thinks I'm hot.
And I asked him if he thinks we look alike.
He said in the pic, then he said it's the eyes..
then I said it's our face shape too.and he said yes..
and I said my eyebrows are very dark too..and he agreed.

He also told me my hair is very nice put down and with my fringe the same as my display pic...
and I joked and pretended I was offended, and he apologised saying he doesn't know how to compliment girls...we seemed to get along well in our chats..

In person he'd ask some random questions, like where I lived, my religion, etc..

I'm going to have dinner with him and his band soon..and I'm so afraid to fall in love with him..because he has a gf. I just want to be friends first..
do you think it's ok to be friends?

Thank you!
