Second marriage of my husband

My husband is not satisfied with me and also because of infertility problem he forced me that he will marry again for his sexual satisfaction and also for children. He is job less and little alcoholic. From the starting of my marriage he never used to care me because of some family issues. He never cared about my health too. When doctors used to call him for semen test he never came for the test he never visited the doctor also with me.....otherwise I would hav child if he supported me..... because my family doesn't treat him properly from the starting of our marriage as he is job less... my husband also didn't care me much...we have been married for 9 years one year back he married another woman...now he is only taking care of that lady and alwez only thinking about her....he is not caring me....he is gvg much importance to her and to her family.....bcz even tho he is job less they r treating him very good he said....what should I do to get him back....I lost my father recently and also he lost his mother recently....from observation I came to know that that lady is only caring my husband just because of sex she is not of good character...secondly she always tells negative about me to my husband so that he leave me and continue with her....my in laws also supported him bcz i hav infertility prob.. I can't live without him...even he didn't care me but I cared him like a baby from the starting. He wanted sex more times in a day which I didn't support... Plz tell me some solution I don't want to lose him as I hav no interest in marrying second time...I know love and relationship happens only once in life time...since our heart is one love is to be to only one person..
