AITA for accusing my Incarcerated brother’s plus sized “wife” of fraud??

I (35m) started receiving calls about a credit card under my brothers name. When I asked my brother (33m who is and has been in prison for over 10 years) claims to have no knowledge of any credit cards or why they would have my number. I found out that this was a Comenity bank credit card for Torrid. Ive never even heard of this place but when i found out it was a store for plus sized woman it became obvious to me that this had something to do with my brothers plus sized sketchy wife (40ish f).

She denied it and my brother believes her. She doesn’t deny having the credit card (which i guess is fraud but as long my brother is aware i don’t care) but she denies putting my number down as the contact for the credit card. Her claim is that debt collectors will often contact family members to get information or attempt to get in contact with the debtor and that i have a strong digital print and it’s easy to find my number. I do have small social media for my business and i advertise aswell but i don’t believe i have my personal number displayed anywhere although im sure there’s ways to get it. More importantly when Comenity Bank called me they asked for my brother by name as if i were him not inquiring about him.

All in all the shit wasn’t adding up for me and to get to the bottom of it we 3way called Comenity bank which was a shit show. I got nothing when asking them about my number because I had already had Comenity bank remove my number. And when my brother tried to access the credit card account with his name and social they said there was no current credit card under his name. Once again she never denied having the credit card (in his name) so she must have closed it. But at the very end of the call after it felt like a complete waist of time my brother asked how did they get my number and the lady said most likely someone put the number on the credit card account. I thought that was an enough proof but my brother didn’t sway, He believes his wife.

Unsatisfied i called Comenity bank back and recorded a full conversation with their fraud department. I layed out the whole situation and they said they do not contact family members and the only numbers they use are the ones on the credit card. And their strong opinion was most likely she put my number down for the card, but they repeated several times that this was their opinion and obviously cannot be confirmed. I could play that call for my brother but at this point i really dont think it will change his mind. There’s a good chance hell be getting out this year and hes expressed that he wont be having any space for awkwardness so i can get over it or they wont want to be around me. For me at the end of the day it’s the principal in the matter. She didn’t try to steal my credit or money or anything. No harm no foul, but putting my number down on credit cards isn’t cool. I can get over it and be casual to see my brother but im always going to think she lied to me and him, and i dont want that for him. Also I really want to know if im tripping because im not above being wrong and apologizing. It would suck for such a fluke to mess with me and my brothers relationship once hes out.

Do you guys think she used my number on the credit card or am i tripping yaw? AITA?

MORE ABOUT HER- She has done a lot of helpful things for my family. They have been together I think 4 plus years and in that time she’s made sure my brother is treated as well as possible in prison and has helped him get into programs that get him out early. She’s also been there to help our other sibling in times of need. So i am grateful for those things, but. First off this is going to sound disrespectful but there’s a lot to be said about woman who seek husbands in prison. She’s very attention seeking and from what I’ve heard manipulative. They broke up (partially my doing) for a few months this last year and my brother really opened up to me about her extreme jealousy and how crazy she has been. Their whole relationship wreaks of insecurity which makes sense giving the situation but to name a few things she pressured him to give HER daughter our last name, she pressured him into marriage, she started a foster home which from what i hear was chaotic and unhealthy and is now over thank god. My mom has spent a lot more time around her and has seen her be very dramatic and manipulative to say the least. She caused a weird gossip problem on the day of my wedding with me and my other sibling. To be honest im scared that when my brother gets out she will be the reason he goes back in. I look at their relationship as a ticking bomb and im afraid of what thats going to be like for my brother while he try’s to integrate back into society.
