This relationship feels weird now

Me and bf have been together 2 years. We had fights and disagreements but always talked through our problems and found a solution we were happy with. He is the perfect guy and I wanted (part of me still does) to spend the rest of my life with him. My family loves him his family loves me. We were planning on getting married this year. I don't know where we fell apart but about 3 or so weeks ago I notice he is becoming distance and I could tell something was bothering him. He told me that he is not as happy anymore and he thinks I felt the same way. I am happy with him. I cried for hours, we talked and agreed to work on it and take things slower. We called off the wedding. Now he treats me like I'm a friend. He doesn't want to hug or kiss me when I ask he will tell me no or it will be short. Our sex life has slowed down a lot. I honestly don't think he wants to work on this relationship. I'm going to talk to him again but I feel like this relationship has run it's course. I love him and I always will. It will be very hard but I can make it through. I am 10 weeks pregnant as well.

***to answer a few questions***

-Yes he knows about the pregnancy

-The pregnancy was planned

-He won't do couples therapy (asked before, he is firm on not going)
