I'm sorry I think I wasted everyone's time with my overthinking. I suspect I am NTA and there isn't much reason to believe otherwise. If this post is breaking any rules I understand if it needs to be removed. I was just way too into my head about this because I received one very negative reaction from my friend's sister and a neutral one from him. I'm not good with dating and relationships so when a pretty woman asked me out I guess I had a hard time processing the response I got.

For context a year ago I lost my job and have worked part time contract work since while looking for more permanent work. I had to move out of my apartment and my sister and brother in law have let me live with them since. As thanks I take advantage of my part time work schedule to take care of my nephew and do a lot of the work around the house since they both work 60 hour weeks. In exchange I live here rent free and barely have to contribute to groceries. I feel bad sometimes for how good I have it right now, but my sister, brother in law, and nephew all have said they actually like having me around and kind of don't want me to leave which helps me feel better about it.

My nephew is 7. I pick him up from school and take him to/from his after school clubs and sports when he has them. After clubs a few weeks ago I took him to the gym because he wanted to shoot hoops until dinner. We played for about an hour and while we were there a woman and her son stopped by and she asked if her son could join us. Nephew said yes so I let the two of them take over and the woman and I sat on the bleachers nearby and watched. She asked about my "son" and I corrected her and told her he's my nephew. We made small talk for a bit before nephew and I had to leave. Said goodbye and that was that.

Last week we went again and like before she and her son showed up and my nephew grabbed him and pulled him over so they could shoot more. She and I took our spots on the sidelines and talked some more. She and I ended up exchanging numbers and after some texting for a few days she asked me out for a coffee date. I had assumed she just wanted to keep in touch because the boys got along, but I guess I was wrong. I think she's really pretty and I like talking to her a lot so I said yes.

I mentioned this to my sister and brother in law and they both laughed and said their boy is a great wing man, but when I told my friend while we were out with his sister she seemed to think it was gross of me and said I was using my nephew to score dates. That wasn't my intention, but I'm also historically bad with women and could just be missing something. If I had to guess I've done nothing wrong here, but I'd just like to get some advice while hiding behind anonymity to get some outside perspectives.

AITAH for agreeing to go out on a date with a woman I only met because I was watching my nephew and her son and my nephew get along? Should I have rejected her?
