my dream that is not reality

Not sure where to begin, as a little girl every girl has dreamed of their fairy tale wedding and the flowers and the vows and that kiss that will seal the deal to make you mrs. 
Well, I've been in a very long and committed relationship, we do have children together. We have a home together. We love eachother... but here is the catch. He has zero zilch nada no interest in getting married. He doesn't think it's necessary. He has no interest in getting engaged, Or even wearing a ring for a sign of commitment. 
This seriously weighs so heavy on me because it's what I truly would like. But he is just not interested. 
So my question is has anyone else been through this and could possibly give me some advice? It's such a crummy feeling🙏🏼😢
