3 months ago, my husband of 18.5 years told me we needed to separate. He explained that he had been unhappy in our marriage for 6 years and was at his wits end. I, however, never saw it coming. I knew we were in a funk, but I never thought we would be where we are now. I have spent the last 3 months fighting for my marriage, only to find out that he had a new girlfriend the week I left our house. The really ****ty thing is, him and I have still been sleeping together throughout this entire separation. He keeps telling me that we will work it out, and get back together, but I also know I can't wait for him my entire life either. We have three daughters who are struggling so much that they are having a hard time living their daily lives. My youngest has been talking about self-harm, my middle daughter has been having mental breakdowns, and my oldest is falling behind in school. Part of me is so mad at my husband for being so selfish, but then I also feel like I deserve better. However, my heart still aches and loves for him. Any advice would be much appreciated!
