Should I leave Her Be or keep Fighting to be with her?

It's like i lied a lot. One lie turned into another lie and so forth an so on. One Day it caught up to me and blew up in my face. When my babymama and werent together i was out having fun and hanging with other women. At the same time i was trying to make things work with her.She asked if i had slept with anyone else. Of course some guys would say no. I did. She found out about a couple of the chicks i talked to. Found out about the the ones i had slept with. Except one! I constantly denied this other girl. Okay i moved back in with my babymama and things were going good until something happened. i really dont remember what it was but she ended up calling me at work and asking me some questions about that other girl. I told her i hadn't talked to her a while and i hadn't. She then asks for my myspace pword. I give it to her thinking i had nothing to hide ya know. She went through all my old *** mail and ended up finding out about the other chick. So we go our seperate ways. So i leave and was **** her. Imma go be with the other chick then. I was for about two weeks and ended up trying to get back with my babymama. She sort of took me back. Once again she asked if i was with that other chick and once again i denied it. I figured what she wont know wont hurt her. Both of them end up finding out about each other. Man did all hell break loose on my ***. I couldnt even go home cause i knew one of them would pop up one me.. Fast forward the other chick claims to be pregnant. Fast forward some more she supposedly had a miscarriage. Thats what she told my babymama not me. Any way my babymama, everytime we get into an argument she finds some way to bring up some other girl or something. I know i hurt her ALOT and i acknowledge that. But does that give her the right to bash me anytime she wants? When that happens i go into i dont care mode. Not to long ago i was like when are we gonna get back together. She said never. It really didnt suprise me cause she has given me plenty of chances to prove myself at the same time they weren't very fair but still they were chances. So Lately I've been like really hollering at this women out here. Im not a bad looking guy either so i gets my share but anyway i dont feel any of them. I feel like i gotta do this in order to get her outta my system. Well that **** didnt work. I havent talk to her in a lil bit, but this past sunday she called. Im thinking she's probably calling to curse me out. I talked to her next day and she just wanted to tell me about her weekend because she say's im a good listener. Then all day that day it was about her. From the time i got into my car to go to my barbers house till the time i went to bed. I swear i talked about her with four different guys yesterday. I do love my babymama very much. I know by what you read you're thinking damn! But i do. I may do what im suppose to do or keep all my promises but i do try and do what i can do when im able to do it. Im know im not the best dad but once again i do what i can when i can you know. I just wanna make this **** work yo. I'll swallow my pride and do what needs to be done for us to be a family. Im sure people heard that before. ****, said that before. Without them im not complete. Im really not. And i left out a whole bunch of other **** that happened between her and i. She's good people though. Honestly though i think there's turning back. But then when she'd sit there and remind me of all the ****** up things i did i'd be like okay imma leave you alone cause im not trying to hurt you anymore. then she'd get all pissy. Should i forget about us or try and be the man she wants me even though we might not get back together? Idk im just lost.
