Confused

Today, I dont know why start to miss him.....
It make me EMO.
I feel not used to it which I din receive any msg from him.
So i try to text him at first he got reply, but at the end he say tired and went to slp d.
At this moment, I really feel abit sad.
I just confused, dont know whether is I used to be with him that why i start to miss everythings or I still love him.
I really confused with what I had decided, whether I will regret or not.
Did I make wrong decision?
I really dont know.

Now I start with another guy.
Its total a new experience, which is totally different with what the first him treated me.
Sometimes I feel so uncomfortable, I dont dare to anyone abt it to avoid ppl accusing me that " told you! u are making wrong decision, u will regret!"

But if I regret, I really feel shame to be back with him.
I just feel that i dont deserve him to be so good to me, cos i already hurt him twice, very deeply.

I admit that I not a good girl which deserve him to be good with me.
I know he is still love me he will wait for me...

Will I regret?
Maybe...
