Relationship advice?

I’m hoping anyone who’s in a healthy happy relationship that’s long term, can help with some advice or suggestions. Anything helpful is appreciated! My partner and I have been together for, what will be, 9 years this coming new year. While we still enjoy each others company, love to talk through the day and night, and just in general we have a good time together no matter what we do. Unfortunately, he has lost his “spark” when it comes to us. He said while he still loves me, his romantic feelings for me have started to fade over time. I feel like it may be because of me. We do have two toddlers together though and I know a lot of my focus is the kids throughout the weeks. However, I do most of the leg work when it comes to them. We both also have full time jobs and his can be a bit more demanding than mine, so I tend to take on most of the housework myself too. Unfortunately, by the time we have any alone time, we’re both pretty tired and don’t have the energy for us. We also do not have a village. We have one sole person who’s able to watch our kids in order for us to have this alone time or to leave the house together and it’s not very often that they’re able to do so. We have tried to make things work and improve things we’ve noticed were lacking but we’re still not back in that “I’m so in love with you” level. We have spiced things up in the bedroom and we’re very open and experimental in that department, so no issues there. But (and if you’ve made it this far, thank you for reading!) how do we find ways to take time for each other and fall back in love again? What are some ideas we can maybe do at home while our kids are asleep or a way we can bring that spark for each other back? We will always have love for each other but I want us to get back to showing each other that we do love each other and making sure we find the time to put one another first. And the little things make it even better.

Thanks again for reading this far. I look forward to any advise!
