<human>: So I (M-18) have had feelings for my best friend (F-18) for over a year after she started telling me she liked me while I was still in high school. (I'm now in college and she's still in high school.) She was also dating a cousin of mine who was a female, but said she no longer had feelings for her.  

We tried to make things work many many times and she always changed her mind. (Pretty sure because she still had something for my cousin although she said otherwise). I tried not to be too clingy and be nothing but nice she wasn't 'feeling" it. As time progressed, I got more and more attached and so did she (while still dating my cousin on and off). All this led to more heartbreak that I've lost count. 

I stopped trying, till recently she contacted me again (im now in college) and she's been single for some time. Lucky me right? Since I still had feelings for her. 

We've been talking for months again. She says she has feelings for me and she loves me, but she says she doesn't "feel" it and it's "not consistent" and she can't be "the one" for me. She feels lonely and wants to be happy while so do I. We can make eachother happy, right? Any ideas on what might be going on through her head? 

Why she might not "feel" it or can't be "the one" or why her feelings aren't "consistent."

<bot>: Try to help me clear things up. I'm continuing to move on and get over it, but I'd like some sort of answer or relief.
