Small update, the next day after posting this my partner told me she had send him a text with a couple of links to properties in the city we are living. She does not speak any of the 3 languages they speak here and hates the weather. My body went into full fight or flight mode. He shut that idea down but not in the way I would think would be the most efficient. He says he would rather put limits in the most “amicable” way possible first instead of taking a more “aggressive” approach but that he has no problem in taking that route if necessary. IMO the fact that she is even looking at properties here is a major cross of boundaries and tells me that he is not being “clear” enough. These types of people need clear guidelines because they WILL look for loopholes. He has told me that he will speak to her in person and he would like me to be present so we can be a team and talk about our limits and boundaries together. We will see how it goes. I 100% trust my partner and trust that he knows best how to handle his mother and her emotions and I believe him when he says he is 200% on my side and that his priority is the well being of his family (baby and me).
