Tips on getting that spark back?

After 7 years together, a lot of ups and downs, Im missing that spark we used to have. We still love each other very much but sometimes I feel us getting a bit distant from each other. We've had quite a rocky weekend to be honest and it's left me thinking how I'd love to get us back to how we used to be. We did have a talk because it felt to me that we might be headed for a split. We both said we don't want that to happen but we don't want a shit relationship either, which to be honest.. Its a bit shitty at the moment. I welcome any advice ladies on ways to get it back
