<human>: Been dating a girl for about a month, but we have been close friends for about 8 months prior. Last night we were talking about our pasts and our experiences and she  brought up a language barrier (she is from Russia only been living here for less than a year, but had lived here before during high school.) 

It got me thinking, because I never really considered there a language or cultural barrier mostly because we speak in a language I am comfortable in. I mean, of course I wasn't oblivious to it because she has an accent and is from another country, but in the context of our relationship it hasn't really crossed me. It all seemed normal.

She explained that it is just a small thing and she considers us being "soul mates" but I'm having a a rapid fire of thoughts right now. I'm wondering what else she views as different. 

I am American but of Latino descent and now I'm having insecurities about myself. On social media sites, she talks to her friends from back home and I can't help but compare myself to her male friends whom are literally all tall and handsome. I also recently found out her ex bf was a 6'4, pretty good-looking guy. I am not bad looking but I'm not classically handsome, and I'm only 5'8. Having some impulsive and insecure thoughts right now.

Can you condense the text into a few key points?
<bot>: Russian girlfriend brought up a language/cultural barrier which I never really thought about; now questioning whether or not I am good enough for her.
