My girlfriend [24F] told me [27M] that she's not in love with me. At all.

So I'm 27, been chasing this girl for 6 years. We finally start dating in October last year, and she hasn't fallen in love with me. She likes me. She's attracted to me. But she's not in love with me. <br><br>She says she feels like she's just missing something. She likes me more than any other guy, but she's never been in love with me. <br><br>I'm stuck here, and I don't know what to do. She said she's happy to try going with the flow of things to see if she'll develop feelings, but I've been in love with her for 6 years. And it's honestly really hurtful to hear that someone who you're head over heels for doesn't feel the same way. <br><br>I've told her how I feel, and she has no idea how hard it's been. She wants us to stay together, but... I don't know if i can deal with the notion that the woman I love, a woman who I want to marry, never fell in love with me and probably never will. <br><br>I've suggested breaking up, and she'd rather stay together and try. I've asked her why she doesn't just set me free, and she claims I'm the only guy who she is capable of loving. I told her that's not the same as love... she just won't be single. <br><br>I'm just at such a loss for what to do.<br><br>TL;DR: My girlfriend isn't in love with me, and I don't know what to do.
