help from experienced long term relationship people

I have fallen out of love with my SO. We've been together for bear 7 years. We have sex but don't connect. I miss it but I have no desire. Our daughter is 11 months old and she is my priority. I think this is why our relationship has been affected like this. I just don't feel much towards him anymore. Everything he does annoys me/is wrong. I realize our issues but I have no idea how to fix it or if it's even fixable. How do we fall back in love? Help
