Caught partner lying again im at a loss of what to do.?

Like i said in my post im at a loss of what to do. I have found out my parter of nearly 4 years has once again been lying to me, he has a history of cheating in the past and he has always known how i feel about him contacting his ex's becuase when he does its not a platonic chat. i has seen the emails and text messages they are all ual and about how much he misses them, I went on the computer this morning and on the page was a open email between him and his x wife about how much he misses her and he enjoys the talk they had this is the same women who refuses to get a divorce from and he tell s me he wont beucase she gets mad if he brings it up, we have a 2 years old daughter and i have given up everything moved to his country which is 10,000 miles away from where i am from my family etc i have given up everything. I would have no issues with him talkign to ex's if it was only platonic but its not since our daughter was born he has been in contact with his ex wife a women that he had a affair with that caused his marriage to split in the first place and another women. im just fed up of it. he makes me feel guilty about taking our daughter away but he treats me like crap really bad calling me names and pushing me about and im tiny Im 90 lbs and not barely 5 foot. i feel i have become so cold and i just accept it becuase im not worth anything. people always tell me how pretty i am and they cant believe im with my partner who is 20 years older then me hey ume we are happy but behind closed doors he is terrible to me. because im my immigration status here im unable to work, or claim any benefits i have tried goign to womens shelter but to behonest they are really terrible places. dirty the women there swear and are aggressive not a good enviroment at all. I have tried talking to my partner about the things i have issues with but everytime he just walks out the door and stays gone for days. and i mean literaly everytime. we live in a rural country side and i have no car so that leave me and my duaghter in the house for days at a time so i just keep quiet most the time
