I'm so confused and down

*LONG POST*

Few weeks ago my so and I had a brief split and I moved out with our baby and my 9 Yr old son from a previous partner that my so took on as his own from age 2. It was more of a break just because we were arguing a lot to the point that we didn't want the kids hearing it all the time so we decided for a bit of time out while we had time to ourselves and then worked things out. I was so miserable being away from him and our home that it made me realise our petty problems were not worth losing our family over. We were still in touch and we both said we still loved each other and always would, but he seemed to be not as bothered about the break as I was. There was no other woman or man involved I believe that 100%. I just think the arguing drained him. so I message him and say basically if there's no way back for us or if you've decided you want this break to be permanent then I'd rather know so I can leave you alone to get on with things. He messaged right back saying stuff about us getting back. We started getting on more and sorted some stuff out, few days later I moved back home. We've been getting on fine , no arguing, just happy families. But I've got this feeling I can't shake that he's not 100% on the same page as me. I dont know if he's just had me home for the kids sake or not, and I don't want to bring it up because I don't want to start drama
