Thanks much for clarifying. The "living in MD for different periods" part is slightly unclear since I did not live in MD at all for 2022 (no MD return for me?). So, if husband and wifes' MD tax period differ by 1 day or more, then the MD MFS option is available? Since my MD tax period is 0 days then no 2022 MD tax form is required from me - just spouse?
