Do I like my Girlfriend?

long story short (sorry because it is still long), Okay im bisexual, but this is my first proper relationship with a girl. My GF and I where introdoced via BBM (weird right) through a friend, we didnt instantly hit it of, she thought I was stunning but me not so much, one day we randomly decided to go out and I didnt find her attractive once again but she says the moment she saw me she knew it was me she wants, we had a nice date infact it was perfect. The more and more I send time with her the more attracted I am to her, LOOKS IS NOT A ISSUE TO ME. but th issue is she feels butterflies everytime we kiss to a point she gets a stomach ache and I make her heart keep a beat, I have never felt this. TBH I have never had butterflies for anyone but another girl from my past has made my heart keep a beat or two.
i enjoy the time we send and she makes me to happy and smileeeee. but do I infact like my girlfriend? ( I question it because of all these love quotes I have heard about how one should feel when falling for someone).
What I can say is we have only been ony out for 2 weeks and dating for a month, she left me once and my heat broke.

Just think about the way she makes you feel. If you don't feel good about her is it really worth it? Be faithful though, communication is key also. If she makes you feel good then stay with her, isn't that why we go out with people in the first place?
