Wait what was that coup that america did? In south america I think? I cant remember it

AITA for dating my son’s arch nemesis?

I (29F) am a single mother living in Kanto. My husband’s been gone for a while and hasn’t returned in several years, and my son (10M) has been gone for quite some time, on his own pokémon journey. As a result, it’s been admittedly a little bit lonely around the house as of late, and given no word from my husband, I’ve been thinking about maybe starting to see someone else.

One day, while I was at work, I came across a woman, who we’ll call J (25F) and her group of friends? Coworkers? You see, J and her, let’s just say group, actually used to work for Team Rocket, and on multiple occasions in the past have terrorized my son and his friends for their pokémon. (I’ve actually met them before on a few occasions.) However, they assured me that their boss had fired them and were now done with the criminal lifestyle. They’re actually really nice once you get to know them! For the past couple of months, they’ve been helping me around the house (they needed a place to stay until they got back on their feet) as well as the restaurant where I work. They’ve even been helping out my neighbor, who’s a professor, with some work around the lab.

But to make a long story short, after really hitting it off, J and I have started seeing each other romantically. However, I’ve neglected to tell my son this while he’s been on his travels, so it came to a bit of a shock for him when he came home. I keep trying to convince him to give J a chance, and that she’s no longer affiliated with Team Rocket anymore, but he’s still convinced that she’s “up to no good”. What should I do? AITA?
