Honestly, that’s normal in a long relationship because after being together for a long time, it’s natural that there are moments when you both start to feel bored or “used to” each other.
I think what you need is to talk to each other and make time for quality moments together so you can bring back the excitement. Also, take care of yourself—make yourself look good, feel confident, maybe try going to the gym. That way, you can attract your husband’s attention again and bring back the spark in your relationship.
