Wedding issues

Hello all.

My fiancé and I have been together over 5 years, engaged for around 1 year. We are getting married in less than 2 years and I was looking at wedding dresses online, he was looking with me. I was saying how I like a long train, he said “you really need to be that extra”

I replied we are getting married, it is our wedding day & I can wear what I want. He ended up falling asleep. Later that night, I mentioned to him how it hurt my feelings that he said that and just fell asleep like he didn’t care. His response was “I don’t even understand why you need to look now, you have 2 years” I don’t even know what to do. He’s insensitive and flat out mean sometimes. He doesn’t really care about anyone but himself.
