Hi there PeachCream22, I'm Sluu.

While I may not be the expert, on relationships I have experienced this type of "can't seem to stop caring about him" sort of thing.

It sounds like you still have feelings for him. And he still has feelings for you, however he's in a relationship with some girl? Or are we talking about feelings for each other but just...friendly feelings? Either way. My advice to you is to stop talking to him. STOP. TALKING. TO. HIM.

If you've tried to be friends but can't...that's a warning that you might have to go a little longer than 2 weeks without talking to him. Because right now it doesn't seem like you've moved on. And you need to move on. Do it for you. And him. I know it sounds harsh, but if you really truly want to get over someone...you can't keep talking to them. You're going to miss him terribly and want to talk to him terribly, and this doesn't mean you still can't be friends...but if you've been separated for a year and you're still not over him. I think that means you've been around him to much. You don't want another year to go by and still be having an on-again off-again friendship/liking each other...

Use this time for yourself, try something new, meet new people. I know it sounds like it, but I'm not telling you to erase him from your life, you'll always care about him. But you can't start being friends again until you're over him. REALLY over him.

And uh, well, that's my advice. Best of luck with your endeavors.
