I would not be so quick to judge. Unlike Pensador, Fiscal has not posted the reason(s) for them opting to move to separate AirBandB's.
I repeat....relationships will deteriorate over time when chipped away one stone at a time.
The reason is that she became increasingly emotionally abusive during the quarantine, I asked her what was going on, she told me she doesn't love me and hasn't for a long time. We had a long calm discussion about why she was continuing to be in this relationship, and she said, I am happy most of the time but I wonder if there is a better relationship out there for me with more romance. She said maybe an open relationship would be better. She then completely withdrew from the relationship and the "family," leaving our child with me for 8+ hours at a time (while I was trying to work remotely, field calls and Zoom meetings). I eventually said, what is your priority, your hobbies or your child and this family? And I said, "be a mother and spend time with your child." And that really set her off and we did not speak for a day, and then the next day, she broke up and demanded we move to different AirBnBs.
Do I think she is a bad person for breaking up with me? No. I helped push her along in that direction by asking her why not seek out the super romantically intense relationship she truly desires. But that doesn't change the fact that she has interjected our child into this mess as a weapon and source of power. And I know it will first be about me staying to basically doing 8-hour plus "turnos" (as she calls them) spending time with our son until she can get a flight to Argentina. I said why not let me have our son, and she said simply, "No, he is mine." Then it will be about the amount of money she receives. Then what?
Yes I am partly to blame for this situation because I had a feeling she didn't truly love me but I never ended it, and I kept going, knowing there was a risk that this would happen. I am a fairly normal looking person and not super rich. She is much younger and quite beautiful, and I knew there was an unbalance in our relationship I had lengthy sessions with two couples therapists who, initially, my wife also saw with me but then stopped, who basically said the same thing. One was very interventionist and told me to end it before she did, in a really bad way that would hurt me. I didn't listen.
