<human>: Can you condense the text into three sentences or less?

Around a month and half ago, I met a girl on Coffee Meets Bagel. We hit it off and get along really well. We have been on several dates since then and like each other a lot. We communicate really well and talk about everything very openly. We have progressed pretty far both emotionally and physically. 

A little background: I am a little shy/introverted/whatever and haven't been very prolific in the dating game for various reasons. She is my first girlfriend and someone who I really enjoy being with. She has had a few relationships (~2-3 I think) before this one and is generally more experienced with this stuff. 

Last week, she asked me whether I really liked her or whether I just liked the idea of being with someone. She suggested that I go back into the dating pool, go on a few more dates and see if there is someone else that I click with. She wanted to keep dating, but wanted me to explore more girls to see if I also like someone else. Her reasoning was that our relationship is going really, really well (based on her previous experiences) and she doesn't want to be hurt later on if I don't actually like her. She said that she doesn't want me to regret not being with anyone else and start to resent her for that after a like six or so months. She said one of her friends was in a similar relationship and the guy ditched her friend after a few months for this very reason.

From my point of view, I am not really interested in looking for other girls and I do really like her a lot. So reddit, I need your advice. What should I do? 

Thanks for your help!
