Confusion about boys

Ok so… There is this guy… His birthday was today. Well he asked me out and I knew it was coming, and I told myself that I didnt love him, but I could learn to right? And well he asked me out, and I said yes. He is the most sweetest guy ever, sweet cute, he has got everything anyone wants in a guy, and yet there is just something that I… Well I dont know. You see I thought I could learn to love him? And well even though we have been only going out for two hours… So much has crossed my mind. I know he loves me so much! But the thing is, I wonder if im ready for this type of relationship again. Ok, I may seem ridiculous but its truth so here it is. I well, loved this guy named justin, we dated for 4 months and 2 days, I know doesnt seem long, but I loved him from the start, I swore he was the perfect guy for me, and that I would one day marry him, and we would just be so happy together. Well, we broke up august 4, 2007, its not april 27,2008, a normal person would be over them by now, but im not!!! And its seems wrong to be in a relationship, but I have an issue with saying no to people and especially cause it was his birthday… So I need some major advice, I feel positively horrible about breaking up with this amazing guy chris who is head over heels in love with me. But how can I carry on with a fake relationship… I hurt him once before this way… But I think that maybe justin still has feelings for me… And well I dont know if he does, but I guess I hope he does. adn well justin is kinda suicidal but the thing is, is that I think being in a relationship with chris is pulling me away from a frienship with justin. And I do know for a fact that justin has my heart… But here is the other catch… You thought that was bad, ugh!, well my best friend is in love with justin, and I do believe so, that I am. I have tried for months to get over justin, but it doesnt seem possible. You know I think that justin may still have feelings for me, but would never date me again, because his friend chris, loves me, and well I dont know if I could date justin cause my best friend loves him. Its all so confusing and blah… I really want some advice, I think I would def rather have a friendship with justin, then date chris, adn I know that if in the middle of like a 2 year relationship with chris, fig. Speaking, that if justin wanted me back, I would go running back. I think and feel that chris deserves better, but he doesnt feel that way. And I just dont know what to do… Def. Need some advice, and I need it soon…

Some one help!!!
