Confused

Hi All , Thanks for your reply ... some of you must be wondering why I am thinking about separation , before I go into details let me tell you my H is the type of person who will go to any extend to please an outsider, he loves it when people say he is the best, so as far as friend and family is concerned he is the best husband. It took me 11 long years to convince my own parents and show his true side. But when he is alone with me he is a totally different person . Anyway I think can handle that , but What broke my marriage is constant lying : You really have to stay with him to know he is lying , he is so efficient with it , he even lied about his education and job at the time of marriage , Sexting : He is always sexting and in some of his texts he had mentioned meeting the girls, he claims he just texted but never meet them , but like I said he is a liar so hard to trust him, and he also claims he has stopped, but he is always texting so I am not sure how to beleive him . In the 11 years of marriage he was jobless for almost 5 years , once he will pretend to go to job when I will go for my work and then he will come back home , lot of drama like this has happened.He never accepted he was wrong and always thought I am over-reacting , I even suggested counselling but he refused. Now a days he has made my life hell, he tracks every moment of me , he had bugged my phone so I had to switch to company phone, he hacked my Facebook and got to know my school friends profile, he then uses a fake internet number and messaged me , I thought it is my school friend and invited him home, then from the number started geting nonsense text , so I told him I will report him to police and I told my H also , but he accused me of having an affair, later I came to know it was my H who was texting me.If I talk to any of the family friends, he will say I am trying to get their attention and we are having an affair , but in front of them he will be very nice . He keeps calling me a prostitute and now a days he says I am responsible for everything he did . I swear on my kids I never even thought about another guy. All this is pushing me to depression and a happy girl has turned to a bitter women , if not for my kids I would have died. I am so sad and now I a days I think may be it is my fault that my H is behaving this way . Like I said what is keeping me going is my two kids and in spite of all his faults he is not a bad father, just an absent father because he is always busy texting or he is out with his friends. But still the kids love him and that is one of the biggest reason why I am still in this marriage , even after what happened. But I really don't want to live in this miserable condition anymore. I tried to talk to my H , but he behaves as if there is no issue and in front of other he is like I want to grow old with you. How can any issue be resolved if the other person is not even ready to acknowledge it.

Please let me know if what I am thinking is wrong or if I am over-reacting
