Is detachment also MLC?

Female in early 40s.. since last year i feel detached from everyone and everything. Had some issues in marriage and we are fine now but even then i didnt really care either way what would happen.. i was ok and prepared for it.. Same for life like i dont really care about anyone (except my kids).. i dont care about anything.. i feel content and have often thought if i had to die today i would be fine with my life so far.. except for thinking about my kids nothing else i want to do or do not have bucket list..

I also dont care for any other relationships than my kids.. if they talk i talk. If they add drama i cut off. Its so simple nowadays.

Is this MLC? I feel its probably wrong to not care about anything or anyone and be this content?
