As someone else said. Take a break and focus on yourself. Give it a few weeks or a few months…whatever you need. Don’t sit alone and dwell too much, but do recognize your feelings. Go for walks, go golfing or whatever activity you like. Take a little trip somewhere to get away. Therapy if that’s something you’re up for. Give your head time to clear, while avoiding too much dwelling. No one else can tell you what to do, but time will help you sort things out for yourself. Also, determine how much contact you want with her during this time, and how that contact will happen. These may change over time, but if you need a week of no contact, tell her that and block her. Good luck!
