Hi Worley - sorry for what you're going through, you have my sympathies, just been through similar myself. Met someone online, really, really liked him, was starting to think it could really go somewhere then he said he was really starting to like me too but didn't want to go any further as he knew it couldn't work out. Like you, this one really got under my skin and now feeling pretty heartbroken. Not going to keep looking just now as it's been really hard. Might go back to it in a few months.
But it sounds like there's still a chance with your guy, give him some to sort his head out. It's a good sign that he's told you how he's feeling and if it's right, he'll come back. Hope you're ok. x
