Unsure on how to feel.

I met my husband when I was 17 (2 months from 18) and he was 19(one month from 20) we talked for a few weeks before becoming official and meeting eachothers parents. Now we're 26 and 28 almost 27 and 29. Anyways we met in 2014 and got married in 2019. Then had our only child almost 2 yars ago in 2021 After I told him we were expecting our son we only had relations once. While it made me feel unattractive i kept it to myself thinking it would blow over once our child was here. Unfortunately it only got worse because during labor both my son and I almost didn't make it. So over the course of 2 years including the time of pregnancy weve only been intimate 11 times. During those times it was only when I was shutting down from feeling unwanted because of his fear of me getting pregnant again even with protection. I've brought it up multiple times how it makes me feel and each time ended with the same speech. " I'm sorry I've been really shitty lately. I do love you though" but hearing it the other night I honestly felt nothing and i know that means I've become fully detached. I couldn't even say I loved him back and it's honestly scary to think about what this means. I do love him though, i gave him everything from my body to my soul even gave him another life and for the last 2 almost 3 years it feels like I'm cohabitating with a roommate. I just want my husband back but I'm worried he is long gone. He isn't who i married. I even asked once if the reason he wouldn't touch me or show affection was because he was cheating and of course he said no. I know it wouldn't be physically as he works from home but I can't rule out emotional. It's like im being eaten alive and I'm not sure how much longer i can keep this up.
