Has your partner ever disappeared without a word and how did you cope?

You basically wake up and they are gone and they aren’t answering your calls or texts leaving you with a constant question mark over your head as to why they disappeared without giving you a reason? My ex use to do this to me and she always had an excuse that she had to clear her mind. Yo me it was a bunch of bullshit and disrespectful and shady because I would never do that to a partner , so another reason my ex is my ex. Have you ever been with someone that did that to you? What did you do about it?
