How to get over your first love..?

We broke up 3 months ago...we dated for a year and 4 months. I feel like ive tried everything that everyone has been telling me to do to help me get over him. I've cut him off, meaning Ive blocked him from facebook, I haven't talked to him in about a month. I changed my number, I blocked him on twitter, I even went half way across the United States to Colorado for a little Vacation just to get away... I know that pain is inevitable & suffering is optional, but I feel like I'm doing everything in my power to stop my suffering , and it's not working.. I know it takes time, but three months is a long time... I'm not just sitting in the house either, I'm going out...even though I see him half the time, I spend time with my friends, I do things that I enjoy to do, for example play the game, and go on walks and stuff, but it's just not working. I'm jealous of him because it took only two days to get over me. I found out he had a new girlfriend. I've been having dreams lately that me and him get back together, and it's not just some regular make-up, it's like one of those make-ups that you see on the romantic movies, like "The Notebook" or something lol. With the big, dramatic, Romantic kiss when it happens lol. Anyways, sometimes I feel like I'm good, and I'm getting over him, then sometimes I feel guilty , like everything is my fault, and I caused us to break up. I'm just honestly tired of all of this, and I've never been more aggravated in my whole entire life. I feel like life is too short to be caught up on one person, but a lot of things are also more easier said then done... and I know I'm only sixteen, and I know I'm young, and I know I have more heartbreaks coming my way, but how can I even get through those even I'm not even strong enough to get over my first one??..
