But Most People Reconcile
A relative will mention this eventually, or a therapist will, and the number is real. Most people who spend years estranged from a mother end up in some kind of contact with her again, something like eight in ten, and it's lower for fathers but still most of them. About a quarter of adults have been estranged from somebody in the family at some point. For a lot of women that's welcome news, because plenty of these relationships do change, and some of them change for the better.
The aunt who brings it up is usually hoping rather than arguing. She's watched families come apart and come back together over fifty years and she'd like that for you, and there's nothing wrong with her wanting it. What the number can't do is say anything about your mother in particular. It describes a great many people at once, and none of them is her.
It also counts one thing, which is whether contact resumed. A woman who talks to her mother twice a year for four minutes counts the same as a woman who rebuilt the relationship and now spends holidays there happily, and those are both real outcomes and they aren't the same outcome. So when somebody offers the number as proof that it works out, it's reasonable to want to know which of those she means. Nobody asked the eight in ten whether their mothers had apologized or whether anything was different, only whether the two of them were speaking.
Estrangement often isn't a single break either. It's distance and return and distance again across decades, and a woman who left at twenty-six, went back at thirty, and left again at thirty-four gets counted as a reconciliation. Doing this more than once isn't a failure of nerve. Relationships get renegotiated over a whole lifetime, and some of them only settle into something workable after a few attempts at it.
Going back is allowed, and it's often the right call. People do change, some mothers apologize, illness rearranges what everyone is willing to say, and a woman who's had four years to herself sometimes finds she can be around her mother in a way she couldn't at twenty-eight. The women who do well on a return usually set the terms beforehand, short visits, public places, a way to leave that doesn't need anyone's permission, and they go in expecting a different relationship rather than the old one restored. Going back on those terms isn't a defeat, and nobody has to account for it to the internet.
Some women don't go back, and that's a fine life as well. They have marriages and friends and work and children who never met their grandmother and don't feel short of anything, and the years pass and it stays settled, and there's nothing sad about how it turned out.
So when your aunt says most people reconcile, she's right, and she's telling you about people in general rather than about the two of you. Either ending is ordinary and plenty of women have had both. You can agree with her, and then go on deciding the thing in front of you, which is yours to decide whichever way it goes.
