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

As someone who's only dated one other girl his entire life, I find that I must turn to reddit for some help. I've known this girl for about half a year but recently we've been talking to each other a lot lately, mainly via text. A few of the conversations we've had lead me to believe that she may be interested in me. For the first time in a very long time a girl, who I have strong feelings for, may have feelings for me. By default I feel like I'm less funny around her and less interesting now. Not to mention the fact that I feel so awkward hitting on a girl 5 years younger than me. How do I stay myself around her without being nervous? Where do I go with this considering the age gap? How can I keep her interested in me? Any and all help is appreciated, thanks everyone.
<bot>: I like a girl much younger than me and I don't think I'm doing enough to keep her interested. What should I do?
