sweet heart, don't feel bad...you are not alone in this process....we are all in the same boat....besides, those happy couples that you see, may not be really happy either....that's the funny part of the relationship.....
Unfortunately...online dating can be really tricky....no commitment at all....guys would act really weird....and some are looking for drama....What the heck is telling you "something bad has happened" and then leave you in limbo...that's not good....
I've been always thinking that I want to have a partner in my life....but I've been single for most of my life and still I don't want to put up with some crap to just be in a relationship....being single is not that bad either....you just have one problem being single and you have hope to find somebody....but if you are married to a jerk, then the doors are closed....hehehehe.....
I found out being patient will pay off later.....I dated a guy from online dating and we met three times everything was perfect, then he went for a trip and he didn't call me after that....I was like you thinking what the heck has happened? we had some text between us, and then I figure out if he doesn't call me, I won't bother....after two weeks, he emailed me that he moved for a job to England....and I met him again when he came back....but nothing again....that's what it is....sometimes, things are happening.....we just have to let it go and enjoy the moments of our life....
just don't give it too much thoughts....otherwise, you will kill yourself....
take care
