Is he with me just because of the kids ??

I lost it on my husband last night because he is always working and we never do anything as a family anymore together. It’s always him staying later at family events and me leaving to take the kids home. I watch the kids while he runs his errands and it’s minimal time spent together. He has the kids while I work on saturdays. I told him he makes me feel alone. He does work two jobs and I work a full time job as well. He doesn’t go to bars like that but he’s always gotta go get something done. I ask him to bring the kids or something and it’s too much or he says it’ll be quick.

My family doesn’t live here and I don’t have many friends. He said he would do better and he apologized but I feel like this was my 5th time or so bringing it up. When I finally break down and cry and freak out, now he wants to listen and apologize. He kept asking me if I wanted to leave him. We finally ended it on an ok night but he was upset afterwards I didn’t show him much affection. And he just said he didn’t want a weird vibe between us… so I text him asking him why he wants to put in the effort and what makes me his soulmate after 8 years and this was the response. It honestly made me feel like he’s in it for comfort or because he knows he has me around to take care of the kids idk if my emotions are getting the best of me or what that I feel some way about this but I need some advice
