I've made terrible mistakes and now caught in between 2 women. what do i do?

about a year ago i was dating a girl we'll call her marry. well marry and i had been seeing one another for a year and a half or so and we started having major issues. we fought too much and hardly talked to one another so i (foolishly) sought out another woman who we'll call gale. I was in another state at the time going to school and it started out completely online. We had yet to meet and i started to feel extremely guilty so i tried to break things off with marry because of it. Well one thing led to another and we ended up having weird sex. Finally school was over a few weeks later and I went back home and met up with gale though I had yet to break things off with marry. Gale and I had sex of course and i began to cheat on marry. Finally after two or three weeks of lies i couldn't take it anymore so i broke things off with marry (never telling her why) . after a few months I was still with gale and she and i decided to move in together. I later found out that marry had conceived the night we tried to break up and this is where things get really distorted. Marry and i make arrangements to share custody and everything seems okay however marry and i begin talking and i finally tell her why i left and explained my actions and she takes it as any rational human being and we don't talk for a while. finally around November she gets into contact with me and tells me that she will leave the country and not let me have a chance with my child if i continue to stay with gale. Gale and i are about a year into our relationship and happy and in love at this time. After telling gale and weighing my options I decide to leave until my life is in order. I inform marry of my decision and she then invites me along on doctors appointments and the like and I'm there for the birth and all that a few weeks later. I then start to contemplate my decision to leave gale and i'm still very much in love with her and I'm starting to miss her. A few days later she calls me and tells me she too is pregnant and my whole life seems to be destroyed despite the fact that i would have loved the news if the circumstances had been different. I've yet to tell Marry and Gale was having a hard time coping with my absence and has moved back home to another state. I miss gale very much but i know if i decide to be with her marry will not let me see my child to whom i've grown very attached but at the same time I want to be there for gales and my child. My name is on the birth certificate of the child i have with marry. I know this seems foolish and dramatic and believe me i've called myself every name in the book and i need not ridicule but guidance. Gale has stopped talking to me because i have yet to make a decision and i really have no idea what to do. Help anyone?
