Lost, lonely, and confused.
A few months ago I met the girl of my dreams and we hit it off immediately. I never believed in love at first sight until I met this girl but that's what it was. After just a couple short months and out of the blue ends things with me, I was so absolutely devastated, but since then, multiple times she has come back in my life, built up hope for me by telling me she misses me, spending time with me, etc. Only to change her mind and take it all back saying she doesn't have feelings for me and we can't talk anymore. The most recent was just a few days but this one definitely feels like it's for sure the end and I am having a really hard time dealing with it. I know it's nuts to be so in love with someone I've known such a short time, but I truly feel like she was the one, like this was a once in a lifetime thing and now it's gone. At best now I have this unbelievably high standard I'm going to expect to feel like in a relationship that I'm scared I'll spend my entire life trying to find again. How do I pick up my spirits when I feel this way? I'm so absolutely crushed.

First off, I'm sorry to hear that you're going through this
. It appears to me that she is having a difficult time making up her mind about what she wants in her life ... but that's not your fault.
I've pretty much given up on pursuing romantic relationships mainly because I'm afraid about getting hurt and I've also had people "ghost" me who I thought I'd get along well with, so I know how bad it feels to be led on.
I believe the most important thing to do during this time is ... take care of yourself. Find something that you enjoy doing and then do it, even if it's by yourself.
For example, I like to try different coffeehouses and restaurants, so if I have time, I'll go ahead with that even if I'm going by myself ... I can always log onto 7 Cups and post & chat while I'm enjoying a coffee and donut. 
If you feel that you must be involved in a romantic relationship AND you are thinking about trying online dating ... I would recommend stating in your profile exactly what you are looking for in terms of character / personaility traits so that you find someone who you are more likely to be compatible with. If you like to read, you can put that in your profile and maybe find someone who also likes to read. If you like going to music festivals, you can put that there and find someone with the same interest. Romantic relationships, in my opinion, will be less likely to flame out if you both can consistently share something in common.
Well, that's my two cents!
Best of luck!
