Never felt so happy.?

So about 6 months ago, i was with this guy and he made me feel like a complete princess, because we live around the same area i see him everywhere, it ended on bad terms as he lived in my house and i had to kick him out because of my ex bestfriend, yea he was seeing her behind my back its a very long and confusing story, but latley he is all i can think about, and how happy he made me feel, i have had a relationship between then and it just didnt feel the same. I no i just really need to get over him but i just cant. My mum and his nana are great friends and talk almost everyday, and his nana says that we should talk about everything and try working everything out, but i dont know if thats him or his nana talking. Please help me as i dont think i will be happy again unless im with him, yes he did wrong seeing my friend and all but i really think we could work it out.
