Don't what to do

My wife and I have been separated for almost a year after her numerous affairs. She was diagnosed with bipolar and borderline personality disorder.
She had told me in the past that she was addicted to pills after some guy she messed around with got her her talked into stealing pills from her job.she is a nurse and was until recently the director of nursing at her job but got fired.she won't tell me why but I got a phone call saying that meds were missing and they told her to take a drug test and she refused.she is now a nurse somewhere else.
So here's the problem. We had actually agreed to talk about things and to get help with everything but when the time we agreed upon to meet she cancelled. Since then I have met a wonderful woman who I don't have to worry about not trusting like I didn't trust my wife.now she is trying to make me feel guilty for moving on with someone else. We have 2 children together 1 day we can get along fine the next we are fighting really bad.i have a feeling that with the way her moods are that she is using something and I really want our kids around her since I don't know if she is using or not.im in the process of filling for divorce and really can't afford a lawyer to fight to get custody of my girls but I need to know if there is any way to have to make her do a drug test to prove she's not on drugs?
This whole thing has been very painful to my girls and I watching her spiral out of control. She lies about everything and I have my girls alot more than she does.we were together for 15 years and I really dont know what happened but I know it's time move on.any advice would be appreciated

Hi mhorn78,

This is a very challenging situation right now.

I would like to say first off, how much I admire how you are protecting your 2 children, admist all the challenges that you face, your children are a priority in all of this.

You place their wellbeing first, and this speaks volumes to me of your moral compass.

It must be hard to watch your ex spiral out of control.

And even harder to be torn between the out of control behaviour and wanting what is best for your kids.

I understand that money is an issue in finding the best possible lawyers.

So I just thought that I really wanted to add that despite what happens, please keep your eye on your most prized possession, as you already do, your children.

I am so grateful that you have their best interest at hear.

Wishing you good health and inner peace and you transition through this.

Thank you.my girls have always been my top priority since they were born and I will always protect them the best I can.i know i can't keep them away from their mom since I know they need both of us but I want to make sure she's not using something that could put my girls in jeopardy when she has them.

If you believe your wife is on drugs and worried for your kids you should get a restraining order. You can talk to someone at your police station. I've been through family and other relationships with abusers of alcohol and other drugs. Protect your kids and yourself. I hope the best for you.
