Husband was unsure

Devon
My husband has been kind of disconnected lately and after speaking to him I discovered why. He said he feels like there is a disconnect between us. He says I have changed and am not the same as when we started dating 6 years ago. He thinks I have become negative and I have lost my self confidence which is something he's always loved abt me. When I asked if he wanted to be with me he got very emotional and began to cry and said he didn't know. That he still loves me and cared for me but something felt disconnected between us. After a good hour and a half discussion we came to the bottom of it and things seem to be good. We r gna work through this and r both going to work on a few things. We both believe this is a phase and we can work it out. I am currently 5 months pregnant with our second child. Which he thinks may be a part of it, that I haven't been as focused on him. We went through same thing with our first. Anyone else ever go through this?
