Is divorce appropriate for a wife’s casual attitude and lack of interest in home and Islam?

I married six years back. My wife is a converted Muslim. Alhamdulillah, I have a son of 1 yr. I work in a Pvt. Co. and she is also working with another co. My problem is my wife and her casual approach and attitude towards me and her life. My parents were not in favour of this marriage and still they are not supportive. Since marriage itself, she is not interested in managing homely things, several times I have opposed to this but she says she gets tired, she doesnt observe purdah despite of my repeated requests/warnings, she never take interest in reading, cooking, cleaning. Last year, Alhamdulillah, I have been gifted a son. My worry is that she doesnt have any Islamic value attached to her, except offering Namaz, she doesnt know anything about Islam despite of several requests/warnings. I provided her infrastructure for that too viz., books etc. I wonder what she would give to my son. Second thing, she has relations to many na-mahram people in her office life, she even has relation with my friends. Just for instance and you to notice the importance that I have in her life, one day she was going to her office with me on my bike, the bike got punctured, we were walking to find a place for repair, all of sudden I saw she was going on another bike with an unknown person. This is mere a one example, she has done these sort of things in past also but of no use, I was shocked, since then I am not able to forget that episode. Even then, she is not bothered about my pain, she is happily enjoying her life, laughing, playing with son, she pretends as she is nowhere bothered about the issues of her & my life. Also these days, for last six months I am facing financial crisis, I have debts more than 15 lacs and income is limited. Sometimes I remain penniless for 10 days or so. I need support either it is financial/mental, but she doesnt care about that too. I am all alone and seeking help from you blessed people. I dont feel like living anymore. Should I divorce her? May ALLAH (SWT) guide me! I am hopeful for your advice.
