Today me and my fiancée split up. We were together for 2 years a 6 months. We also have a 6 month old little boy that is my pride and joy. Me and her have been having our differences and arguing for a while now. We separated 6 times in a 2 week span before this. We've been arguing for a few days and last night she said she was tired of me, so I said I'm tired of her and ended it. I told her I was done for good.
As of today she has been begging me to get back together with her. I love her with all of my heart and more, but I just don't think that it would be the best decision to get back with her. We have been through so much, but at the same time I don't think that its enough to fix us. She keeps saying she will do anything for me, but I answer to her: why now?
Why after all of this does she want to change? Because she lost me? Its happened before, why now?
I just don't know what to do. I'm only 17, I'm in such a dazed state. Please don't judge the age. Its hard being this young with a child and maintaining a relationship. Please help

How old is the girl ?

I would suggest couples counseling and trying to establish a relationship
