Feeling lost

Husband and I have been together for 12 yrs and married for 10. We have 2 kids 15yrs and 6yrs. I'd say for about 4yrs we have not felt very close. We don't have fun together or have any hobbies we share. Lately I have felt like I'm losing my love for him. There is no spark. He is an amazing man and father. I have no desire to have sex with him or be intimate. We have a great life but most feelings are gone. I feel like we are just coexisting. I try to make myself have sex to see if the feelings are there but there's nothing. Not sure what to do, thinking about counseling. I just wanted to talk. Thanks for listening
