<human>: Can you give me the gist of the text in a nutshell?

My first TIFU so sorry for the mistakes

So like many tifu's this didn't happen today but a couple months ago, I'm a 17 year old male who has never had a girlfriend (I know pathetic right). So my friend invited me to see her horse show practice, (they just ride around and do drills for their shows) so I'm walking with her cousin chatting it up, when I see this really cute blonde girl, so me bieng very shy and nervous did not approach her all day, so my friends younger sister got her number for me she must've known that I liked her(she's the real OG), texted her the day after we hit it off fairly nicely and I asked her out on valentine's day, to which she said yes.

 So after a couple of weeks of going on a few dates, I started thinking to myself and came to the conclusion that she doesn't like me and put me in the friendzone, I decided to seek wisdom from a number of people, as I said before I've never had a girlfriend so I don't know the ropes when it comes to dating.

Here's the FU, I lent my phone to one of my friends who decided to test if we were actually going out, and to my suprise we were I was overjoyed my fellow redditor's, but what happened next proved to be my downfall and my realization on how much of a rookie I was, I told her my feelings for her,I mean we have so much in common and we get along just fine, but it still wasn't enough to save me, she said she wasn't ready for the next level and wouldn't have the heart or time for me, that shit hit me harder than a giant in skyrim.

I thought it couldn't get any worse, but as Billy Mayes would say "but wait there's more!" Turns out she was a lesbian, yup I dated a lesbian, she wanted to apologize for leading me on and that it was stupid for doing that to me and hopes we can still be friends, I just excepted my fate and agreed. I feel so dumb for letting this happen to me, I don't think I can ever date again.
<bot>: dated a girl for a couple of weeks, only to get my heart broken and find out she was a lesbian who was leading me on, and my dating life may also be ruined. (Sorry for the length)
