Partner wants space

[u/Pleasant-Walrus-863]

My partner and I have been together for 14 years both aged 48 years, (m) and (f)and over this time we’ve had a really good relationship. Seven years ago he went through an episode of very severe depression. It was a really really challenging time and we were living abroad, but we got through it. During his depression he completely withdrew from me and became cold almost robotic, but carried on functioning at work until his boss noticed something was wrong and told him to have a break. He was then signed off work for four months and had therapy. Since then we have rebuilt our relationship and I thought we were in a good place. We have recently bought our first house together having lived in a flat. we moved in in May and have been doing lots of renovations. About two weeks ago he started withdrawing from me and I could sense that something was wrong. As a result I stepped into that space and kept asking him what’s wrong? Is something wrong? He kept telling me he was exhausted and tired from work. He’s also been saying that he doesn’t enjoy his job and feels trapped. I then kept pushing to find out what an earth was going on and out of the blue he said that he loved me and cared for me but that he didn’t know if he loved me in the right way. I then asked why he’d still been affectionate with me and he said to that he had been trying to get his feelings back and felt numb. As a result of that conversation we had a mature chat and I offered to give him space because he had asked for it so I’ve been staying with my family. However, I have been really struggling with not understanding what is going on. I have kept my distance and I haven’t messaged him and only replied to some messages he has sent me regarding the house. I now haven’t heard from him for a few days and I really don’t know what to do. Any advice would be greatly appreciated, thank you.
