Feel so down

Haiz.. dunno how to start..everyday also feel stress.. this is my life for the past few days. 6 days ago i broke up with my girlfriend because of some reason and now i feel like i have already fall in love with another girl. Few days ago, i already told her i love her than she was considering weather want to accept me anot but the worst thing i did in my life was i made a wrong move. Yesterday i told her i wanted to step back from this relationship and be back like normal friend. The best thing is i still love her but i dun dare to confess anymore because she keep sayin that i am not loyal enough and playing with her feelings. I am not playing with her feelings. I just scare me and her will argue if we really ended up together. I am a smoker, useless guy that only know how to talk and she is so quiet and keep everything in her heart if anything happen. We are like from different world. I am just not suitable for her. All i can do is to be beside her and help her whenever she needs me. The main reason why i step back was because i was too childish. She keep saying that i am a flower heart guy so i got pissed off and i said i wanted to step back. If i can be more patient and care about her feelings, nothing will happen between me and her. Wat a stupid move. To be honest, I am not flower heart lu, i am just good in sweet talk. I just enjoy sweet talk with girls but if u wan me to change, i dun mind to change. haiz. It is too late to regret. The only thing i can do now is to be 24 on call and help her whenever she needs me. I hope i will be the guy she will find, if she need help. Hope she can forgive me.
