Confused on where to file state taxes as a military spouse

My husband's (service member) home of record is Kansas. A while back, I went through the process of changing all my stuff (license, etc.) to Kansas as well to both be Kansas residents. We file our taxes jointly. He just changed his state of residence to Texas, as that is where we will likely end up after he retires in a few years because that's where my family lives, but now I am totally confused. We are currently living in California for his orders and will be here a few more years. I am a 1099 employee. Is there a way I can also claim Texas as my state of residency? Am I still allowed to keep Kansas as my state even though he switched his or does that now nullify my spouse right to claim his state? I imagine not at this point because I am registered to vote there, have a DL, etc. However, we did all these changes way back when so we could simplify everything and file everything easily, but now it's back to slightly more complicated. Basically - is there any way for me to also claim Texas? Or do I just keep Kansas and we file state taxes separately?
