She's just another girl

After months

I know, I write every 1000 years, and since I begin to write about him by now all the things seems so different, do you remember my friend? Yeah he is my boyfriend now, but that's another story. Recently I've been so happy with him, my life was kind of perfect but when you think that everything will last forever your past come back.
I was chatting and when his chat appeared I was like "that's not true" I wanted to cry but I was strong and answer him.
We started to chat but he always was talking about our past, and telling me old nicknames that I had forgotten. It comes worst, he talked to me in the school when I wasn't with my boyfriend and hugged me, it made me fell so nervous as all the death butterflies were zombies now, exactly this is how I feel: zombies in my stomach.

He invited me to a date, of course I didn't go. I needed to tell to my boyfriend what were going on, by the way I got boyfriend I will talk about it later. So I tell him, but things went wrong. He was in love with another girl who made him feel like... nothing, he give up and now he is with me but now the girl is jealous and wants him back. Does this sound familiar to you? We were in the same way. I swear to not leave him, he says he did too, but he agreed to go in a date with her? What could happen?
