Sorry for the length - I just want to make sure I'm painting the full picture.

Background

I have primary custody of my son from a previous marriage, and he must to go to school in whatever school district I live in. The separation/divorce was in 2011/2012 (he was 5) and was particularly hard on him. His mother has some significant mental health issues, and as much as I have tried, his mother and I are unable to have a stable, amicable relationship. I know this takes a toll on his well-being and although I can't force an amicable relationship with his mother, I've done my best to provide a stable home/life when he is with me. I have striven for creating a consistent routine and my son and I have a good relationship and healthy communication, but he has obviously been deeply affected by the entire process.

I met my SO three years ago; she has a young son that was not school age at the time. Not shortly after we started dating, she moved closer to me (her lease was up). However, she is extremely close with her family and this move put her roughly 50 minutes away from them. It became a major issue; my SO suffers from anxiety and depression and the distance from her family was really taking a toll on her and our relationship. As her lease was nearing the end of the first year, she wanted us to move in together but also wanted to be closer to her family.  Her preference was to be within the same city as them and approximately 10 minutes away from her mother and two sisters. At the time I didn't want to move my son out of his school system. He was just starting fourth grade and because of the divorce this was the second school system that he was in. He had friends and he and I both enjoyed the school, teachers, and staff. Moreover, if we would have moved to my SO's preferred location we most likely would have had a court fight due to distance from my son's mother. Against my better judgement my SO and I compromised on a new location that was known for having a stellar school system and that kept me in a range that wouldn't cause problems with my son's mother or the court. Our compromised location put her within 20-30 minutes of her mom and sisters. We agreed that this move was supposed to be our final major move and that the goal was to plant roots in the community. We have lived in this community for a little over two years now (her son is in first grade here now and my son is in sixth), and my son has started sports here. 

The Breakdown

Ever since we moved my SO continued to hint that she would rather have moved to her preferred location. It was never a huge fight, but it was apparent that she still wasn't happy. The time came that my SO's mother decided to move and she moved further away from us and closer to the other two sisters. We're now approximately 30 minutes away from all of my SO's family, and our relationship has struggled ever since. My SO has essentially given me an ultimatum that we need to move closer to her family again, which means a new school district for the kids. She explained that family is crucially important to her, and that she can't imagine raising a family (we were discussing having another child) this far away from them. It has gotten to the point where she says that she is willing to end the relationship if I am unwilling to move again. Her argument is that our two boys have cousins that would be in the same school system (although none of them are in the same grade) and that we could have more impromptu meetups with her family and they could "play sports at the same parks together."  I understand the importance of the relationships, but my son simply does not have the same deep relationship with her sister's children as my SO's son (obviously). He was older (and had had no other brothers/sisters/cousins) when he met them and has never connected as well as we had hoped.

I absolutely love my SO, but I also have a duty to my son to continue to provide stability. I don't want to rip him out of yet another school especially in middle school when kids can be so horrific. I think moving again would wreak havoc on him and his emotions. Outside of my own feelings towards moving again, I'm not even sure that the court would let me due to the increased distance to my son's mother. I could see her argument if we were hours away from her family, but I can't justify a decrease in 10 or 15 minutes of travel time at the expense of my son's well-being. I'm trying to empathize with my SO, but it's hard to feel like she is putting her own feelings in front of my son.

tl;dr My SO wants to move to be 10-15 minutes closer to her family but it would involve switching my son's school for the third time. My son has already had a tough childhood.
