How much longer?

Alsalaam Aleykum brothers and sisters. I am hoping to get an answer to my question from some the scholars who might be attending this forum.

I am a Muslim American, I was married to a Woman for 20 years who converted to Islam on her own accord before we were married. towards the end of our marriage she became uninterested in the marriage and left our home and took our children to another state without my permission.

After a battle in Court, I was awarded sole custody of our kids, the courts granted me full control of the mother's visitations and I was able to recover them from the State my X wife moved to. She was also refused alimony and all our properties went to me.

Because she never worked during our marriage she has had a very difficult time getting a job and I have supported her for the last 19 months. She had not seen our kids for 15 months and had never asked to see them or invited them to go see her. She rarely calls them and she only ever does when she wants me to give her money.

During the entire time I have been supporting her I continued to ask her if she is still following the teachings of Islam and she assured me she was.

2 weeks ago, my youngest son who is 7 repeatedly asked that I take him to see his mother as he had missed her terribly. I connected with her and she agreed that we visit. I booked 2 rooms in a Hotel in her town and we visited for 5 days.

She seemed very indifferent to the kids and was more focused on trying to reconnect with me. I have no more desire for her being in my life though and the rejection was upsetting her terribly.

During the visit I paid her apartment rent and gave her enough money to cover her bills.

On the last day of the visit, she informed me that she is involved in very obscene sexual activities, excessive alcohol abuse and experimenting with drugs. I never asked her, she simply volunteered this information.

This information upset me, I did not say anything and we left in peace.

When we got back to our home state she contacted me asking me for more money. I refused, I told her I cannot participate in her activities, for me to provide her with money so she can spend it on Alcohol and lewd conduct is against my faith and personal beliefs.

Am I out of line for stopping to support her? We have been divorced for 16 months now, I have paid her Moakhar ($5000) already and have given her so far more than $28,000 in assistance.

What does Islam require of me in this situation? She has no one to help her, she is uneducated and had relied on me most of her adult life. Her father is dead, her mother is an alcoholic and has major drug addictions. She is an only child with no siblings.

Part of me feels guilty for no longer wanting to support her, does it make me a bad Muslim or am I going against the will of Allah for stopping all support now that I found out what she is doing?
