We were together 18months, had one mayor break up, and one small break up.
I had lost my parent in that period, and one member of the family tried to have an affair.
All that really hurt me, and I think that during that time I could not give my best to my GF.
I broke up then, and after few days start seeing another girl... I think now that I was out of my mind doing that.
I broke up after one month with that new girl, and 2 weeks later my big GF was on FB chat, she say hi and we talked nice and get together the same day.
It was really nice.
But I could never had the piece because the family issues, and I told her that I feel strong for her, but can't say I love her, to give me some time. She agreed.
20 days ago I was in a really bad mood for a few days and broke up again 3 days before her birthday... on the way home I felt something like revelation... all the pain from issues is gone, and I have clear view of my love to this girl.
I have waited for a few days to be sure of that.
In the meantime I found out that she has new BF!
I called her, she came to me and I told her for the first time I LOVE YOU, I was sincere.
She cried and said 10 times that she loves me, too! We kissed and it was great, she told me she will think seriously about that.I sent her flowers and some nice toy I made her myself (for the first time)

Tomorrow she did not reply my calls or messeges. I was devastated. Finally I can feel love, not grim feelings and she is not there.
But once again, she told my mom that she loves me!

She does not want to hear from me again, told me I am too late and that she has no feelings toward me, and that I should delete her number. She sounded harsh. Tried few days, same. I feel terible.

Please understand that I was a jerk, but I had seious problems, now I can feel love nad she don't want to hear. I understand that I have to suffer as much as she did, but I am ready to if she will come back to me.

My friends say that her new boyfriend is a rebound BF and that she will call me when she cool and when I start to miss her, and that she could not lost her feelings so fast.

What do you think? Is there any hope?

This says it all. She's over the relationship. The new boyfriend may well be a rebound, but it doesn't sound like she'll be coming back to you.

It's time to get on with your life and accept that she won't be in it.
