I'm 45 and was married for 6 years and I'm going through a divorce right now due to his alcohol, mental and verbal abuse. So I understand how you feel in that initial stage. For me, i was fortunate enough to be surrounded by close family members and friends plus my work also kept me distracted. It's now 2 years since I left him and it did got better for me because I went back to school, advanced myself in my career and learning more about myself. It will take time for you, it's not easy but I know you can do it because you already made the first step by divorcing a cheater like him.
