Is divorce the only option

I have been married for almost 8 years. We have been together for 14 years, high school sweet hearts. My husband and I are very busy with work, household duties and with our 3 children. I always try to find time for us but he claims he is too tired talk or makes some other lame excuse. I feel like we go on with our daily routine and continue to grow more and more apart. I have suggested we work out together after the kids are asleep. I offered to attempt to have a date night at least once a month. No matter what I suggest, he doesn't seem interested. Or I end up doing everything to get a date night ready and resent him for not helping. I am very disappointed that he doesn't seem interested in our marriage. He knows how I feel and I have told him if things don't get better I think divorce is the only option. His disagrees, but doesn't suggest anything to make things better. I really believe I am a great wife. I try so hard to make him happy and in exchange I get nothing. I don't want to live a life being ignored. Is divorce the only option?
