Hi Robin- Of course it's normal. There's nothing abnormal about those feelings. You have loved him in the past and love is very strong so it's natural you will think about him from time to time. What I would do though is just forget about the past. You can't change it right? It's good you have loving memories of your ex and there is no need to just forget those memories. However, the past is the past. Focus on the present and be grateful you have a loving husband. Strive to be more appreciative of him in the present moment and everything will work about in the end. Never dwell on thoughts of the past. Good luck.
