I am living with my roommate and I love her. But I am not sure if she likes me too. She gives opposite signals.
Sometimes she is very nice to me. She talks to me about every detail in her life. She sometimes says: "you are awful, you are amazing and ...". She asks if I need anything when she wants to go shopping. She once suggested to wake me up at 12pm, when I had to study all the night and did it in a nice way. She sometimes offers me to watch romantic movies. She gave me a ride to school a few days ago. She suggested me to go with her and rent a movie. She suggested me to go to the pub once.
But on the other hand, she brought boys in her room with whom they stayed all the night, several times. (They were not her boyfriends. Just temporarily friends). She talks about the boys she meets in the school or at work. When her friends and family come to visit her, she does not talk to me.

I am now confused. Does she like me? Is there the possibility that she loves me?

The best way to find out is to ask her. It won't be the end of the world if you do.
At least, this way, you'll have the best answer.

Maybe she considers you a very good friend but does not have romantic interest in you.
Just ask her... when you discuss about you, about her, about relationships, etc. just lead the discussion to this topic and simply ask her.
