So heres the story i use to not be into the whole being in a relationship . ive always been ohkay with being single . i can do whatever . then my bestfriend past away in august &; he use to always to tell me to just try to open up to someone . well that week that he passed away i met this guy and idk we just clicked and he later ended up asking me out on my birthday &; we were together for 4months then i ended it . i honestly dont even remeber the reason why . but that was the second time i had called it quits with him &; this time instead of getting back together he ended up getting a new gf . but through the whole time they were together he always told me how hes in love with me etc . but i couldnt believe him because he had a gf . so i talked to him less and i ended up meeting this great guy named tony . hes my perfect guy . but the thing is that he still had feelings for his ex &; when she found out tony &; i were together she talked to him &; they ended up getting back together for 2 weeks then he ended it cause he says it wasnt the same cause he had developed strong feelings for me . but durning those 2 weeks i had started to my ex again &; he had told me hes been single &; that he wants to try to work things out with me again . &; i agreed cause i missed him but now that tony wants to be with me again also idk who to choose . they both did me dirty . but my feelings for tony left when he left . im just scared that he would leave again . but he treated me like a princess and bought me anything i wanted . my feelings for my other ex , his name is izzy btw , well they never went away . &; hes a ladies man &; he hardly spolies me . so him having way to many girls as friends always worrys me . but im sorry for this beinq so long i just dont know what to do .
