Do you think this girl likes me?

I have known this girl for 2 years now and we hang out about once a month. She likes to bother me and tease me. She started telling me some personal things about her family and her life and i feel sh'es coming on to me. Sometimes she would talk about this other guy too and she tells me about him.

One time she also called me her "brother". We don't text that much but we have fun in person and every time we are together she would try and take a selfie with me for example.

I really liker and am a shy person but would you she likes me even though she talks to me about this other guy once in a while? I tried to figure it pout but it's kept me up at night and I don't know what to do.
