Not sure what to do anymore?

I think the best way to go is to get your friends together and base your free time around them. Don't let yourself be alone because it might start you thinking about your ex. Spend time around people who care about you and want to see you smiling, most importantly have fun! If a guy asks you out who you find decent, it's better to give him a chance than to reject him straight off. By agreeing to go on a date you're not betraying anyone! You will eventually find someone who you can love even more than your ex, you just have to give it a try each time the opportunity comes round. Being single can be so much fun, you just need to look at things objectively and decide what's best for you: whether you want to be in a relationship or whether you're ok being single for a while. You never know when someone will come into your life, you just have to take opportunities when they come! You will definitely get over him, it's still an open wound. You just have to get far away from him, and try to have fun without him, you'll be fine :)
