<human>: Can you give me a shortened version of the text?

Me: 25F American Him: 25M Ukrainian (5 years in the US)

Okay TwoX... I've known this guy for around a year and and a half. We had talked here and there casually in the smoking area at work, but we didn't start seeing each other until after the company Christmas party this year.

We've been hanging out for about 5 weeks and I'm really enjoying myself, but I'm not sure how or if I should ask if we're dating yet?

He works like crazy, but when he does have free time he seems to spend it with me. When we go out or if I'm with him he WILL NOT let me pay for anything. In fact, this weekend he bought both mine and my best friend's (a guy) drinks at the bar all night.

We've talked about our families and I've met one of his brothers, but that was mostly because I was coming out of his bedroom and they live together.

He opens doors for me, tries to light my cigarettes and is very sweet.

A friend of mine who has dated a Russian guy told me that if he's taking me home, introducing me to people, and paying for my friends' drinks as well as mine that he probably already thinks we are dating. Her reasoning was that if he was buying my friends' drinks it's because he feels responsible for me and my company. Is this true?

I know this all probably sounds incredibly silly, but I really like him and I don't want to mess things up by not understanding something he would think was obvious.
<bot>: American girl that's never dated a Ukrainian guy before. Accustomed to being able to read people very well and I don't seem to be able to do that with him.
