why me?

Its only been 2 days since we broke up. He's already talking to other girls. I on the other hand cant find it in my heart to take to anyone else or go boy hunting. My feelings for this guy that I been dating for a year and know for 3 years all together were real and true. It hurts to see him move on. It hurts seeing him as a player. Everything just hurts. He's already looking for my replacement. Was his love ever true, was I ever known to be his love of his life like he told me. I doubt it. At this point I feel like im going to be forever alone and there wont be any happy ending for me after all. I was on instagram and two people wrote be to be honest post. The first person says "TBH: I saw you with your boyfriend there other day you two are really cute hold it down and your pretty." the second person writes "TBH your a very sweet girl and you and that guy hold it down." At this post I just completely broken down to tears I had to make a post on instagram indicating that I am single. I didn't want to but im tired of hearing those things. Me and him got those remarks a lot but I guess I was never worth it to him.
