What do i do? He barely notices me,doesn't reach out to me emotionally? I want to leave but i'm worried about regret?

I'm losing my mind at this point and i could really use sone help.

I met this guy online almost 9 months ago,he seemed like a perfect match,a true gentleman and someone who was intent to get to know me better,admired and respected me .

He came to see me a month later and it became a habit that every month we would travel somewhere and spend a few days together.

He is someone who was in a bad marriage for 16 years but wanted so much to move on and try hard on a new relationship.

He would call at least twice a day,text,e-mail,buy gifts and told me his life revolved around me .

We decided that i would move in from my country to be with him and i moved in 5 weeks ago.

What i saw was truly shocking.

He would sleep on the other side of the bed ,if i tried to touch him he would push me away and his excuse was he couldnot sleep while someone was touching him.

Woke up every morning without a word,

I would use his car so when i pick him up from work he would avoid kissing me and his excuse he was too tired and wanted to go home.

When i cooked something he would never tell me if it was any good or bAd,just someone who sat next to me with his eyes fixated on the tv and wouldnot utter a word.

When we walked,had lunch out and i would try to talk about tge good old romantic days he would laugh sarcastically at hiw romantic i am and tell me now we are in a new stage and we are a family now.we should stick to one another.

When i complain he says its all in my head .
