Im12 weeks pregnant today last weekend me and my childs father had a very bad breakup. He was abusive mentally and physically for years. Ive chosen to stay away from him gor good.I also have a bad back now because of him slamming me on my back on the tile bathroom floor last year. I currently have a 3 year old little girl w him as well. Do you guys have any suggestions of how i can get over him or just simply relax with some self care tips? Words of encouragement are appreciated as well since im now a single mommy. He doesnt support us in any way.
