What do I do next is it a waste of time?

I met my partner two years ago. And we got together and left the country. I was a step father to her two children who I adored (i know I could never replace their own father never intended to). My partner got pregnant I intended to marry her. When we emigrated I had to return to the uk due to my buisness comitments. She I left she has been I think hormonial angry abusive, lier. I have tried to suppor her but have been stuck in the uk. I wanted to return for the birth but was informed dont so I didnt. I have contacted her now the baby is born. We get on on and off she told me in december that it was all over. She has recently asked me to help her with something that is fraudulent but I have informed her that I dont want anything to do with it. I have spoken to her recently and she wants to seem to contact me everyday I am not sure if I want to get back with this women I am not sure if this is even an attempt to get back together. She wants me to go over there but I am not sure. I will go but only to see my baby help
