Husband problem

So long story short :

My husband and I were dating for a year . We have been married for 3 months and I’m 7 months pregnant .

It’s been hard 3 months , we don’t fall asleep in the same room he usually stays until 3-4 am in the living room while a sleep in our bedroom at around 11 pm

Not to mention we haven’t touched each other in ages (little more than a month )

Yesterday I tried talking to him about it and his response was , maybe you should start wondering why I don’t want to sleep next to you

What is that supposed to mean ?

Îv been feeling super neglected, not desirable anymore

I’m super desperate to be honest ,I don’t really know what to do . I have tried talking , arguing , being nice nothing seems to work.
