How do I cope?

I was dating this really nice guy but we took a break because we never saw each other. Well, we lost touch for about 9 months, and I starting seeing someone else. Lets call the new guy Tom and the other guy Jason. Well, I had just started seeing tom a few months after Jason and I had lost contact. A few months into our relationship, Tom started bugging me about having sex. At the time, I was going through a lot with my biological father, and it was good for me to talk to Tom. After about a month of randomly bringing up sex, Tom said he would lover me forever and I would never have to be lonely if I had sex with him. So, I did. Tom broke up with me a couple days later. I suppose it was to be expected. I was ashamed, so, when me and Jason stared talking again, I didn't tell him about it. but a couple years later ( 3 weeks ago) I couldn't handle the guilt and I told him. He dumped me, but I love him so much. How do I move on?

Maybe I'm not supposed to.

What type of jerk would dump you for having sex with someone almost a year after you stopped dating.
Seriously you did nothing wrong here.
I know it's hard, but give it time, you are better off without him...
With time it will get better...
Just go and hang out with your friends, live your life, get rid of stuff that reminds you of him and eventually things will get better.

Im suprised you haven't locked this question yet.

if he dumped you for having sex he would have dumped you anyway. what kind of jerk would do that to the girl he loves? no one. not if they loved her. moving on is SO hard, I'm trying to move on and let go of someone too right now. I don't think I will ever be able to but I guess we'll see.
