I’m in love with my best friend

I don’t know what to do I’ve told him in the past and because we live so far apart he didn’t want to do long distance. But he’s always felt the same way I felt. Just he never told me or expressed it. and he’s told me now that he now has felt the same way. But…. I’m now married it’s been 1 year now and I’ve always loved him and I just never told him. And now I know he feels the same way. I don’t know what to do. He wants me to be nothing but happy and I want him happy too. I just strongly believe we belong together but I can’t come to terms to get a divorce I can’t break my husband’s heart. He’s a good man but I’m not in love I thought I’d grow in love with him but I haven’t yet. I do try to avoid the what ifs and focus on the now. I feel like he lost his chance but it’s also a chance I’m willing to take if we could make things work. He lives in Ny and I live in Florida. We both know how we feel about each other and it doesn’t even effect the friendship or make it weird I need some women advice. Someone who’s has a little more wisdom then I do
