I've been in the same position

One thing I've learned is that you have to control any feelings you may experience. Yes, easier said than done, but it CAN be done and is the best for all concerned.
I had a year of sheer hell. My mental health was affected, my ex kept two of my four children from me for a year (aged 11 and 5), in which time I seen them once, and they were separated from their two sisters (13 and 4). I walked away from 16 years, with a few personal possessions.
To get my sons back, he made me sign the divorce papers saying I wouldn't touch his pension. He used our kids and he'll never be forgiven for that.
But he has no place in my life, no place in my emotions, and I learned to let go quickly, for my own sanity and for the sake of my children.
I picked myself up. I dated, I took up new hobbies, I went to college....put simply, I learned to love life again!
I have now been married for 8 years.
Look forward, not back. Immerse yourself in new things, find yourself again.
