A foreign woman is confusing me to death.

I have been dating a foreign woman for quite sometime now. Dating her is less drama. She's very open minded; that's what I like about her. She always goes with the flow. It's a good thing, right? Our relationship is more mature. I don't have to deal with immaturity. However, the only thing that made me confused is whether she loves me for real or she's just playing around. Everything I do seems so fine with her. One time I told her I'll be out with my friends with some chick. I thought she was going to stop me but she didn't. She even wants me to spend more time with my friends. Does she trust me that much or is doing something behind my back?
