I wouldn't exactly call it an attack, but after the fact that's sure what it feels like. I'm in a graduate degree program, and have a classmate who has a kid. Now, I've never said anything negative about her or her kid. I actually like the kid quite a bit, but he's 4 so after a while I'd like a break. I've had them both over before, and have mentioned that they're both welcome whenever. However, I have never made it unclear that I don't personally want children. It's all fine and dandy to have kids if you want them, but I just don't.

As some background, I like kids. Quite a bit. But I can't have any and have accepted that this is my evolutionary cue that my genetics are a no-go. I still waver occasionally but I'm actually OK with it now. Being on this subreddit has made me realize that it's a perfectly fine choice to not reproduce, and I feel quite a bit better about my childfree future.

As to what happened, I mentioned during a break about taking a class focused on families and divorce proceedings, and she basically told me I can't because you actually have to give a shit about kids. She insinuated that since I "hate" kids I can't deal with divorce practice because I would fuck up a kids life. To keep things short: she followed up with a tirade of how I hate this or hate that and how the things I say are an attack on her. She pulled up the term breeder, which I don't really know how that came up. Again, I have never attacked her, and never used the term breeder so I'm not sure how she got there. All I've ever said is while kids are cute, I like when I get to give them back. Nothing against parents, just "not for me, thank you" when it comes to me having them.

Maybe she was having a bad day. Or maybe she felt offended because she's been peeking over my shoulder while I've been on /r/childfree or other websites and thinking I agree with the entire internet 100% of the time, but I definitely feel like I was unfairly attacked.

It's been almost a week, and while I've been trying to get over it I'm still angry about it. I sit next to her in almost every class, and while we've been acting normally since then I'm still just upset over it. I think I feel even more betrayed because when we first met she kept reiterating how she loves her son, but she's a big supporter of choice and the ability to be childfree. All of a sudden, I feel like she's fine with it until somebody doesn't hide their opinions about not making the same choice she did.

I very well could be overly sensitive as I'm in a high stress environment and I tend to let things get to me when they shouldn't, but I just feel blindsided like I was coerced into apologizing for something I'm not sorry about. I like her as a person but, honestly it's really darkened my friendship with her since now I feel like I can't honestly share my dislike for something or someone without being "negative" and hateful.

I keep telling myself to just build a bridge and get over it, but I just can't seem to. Any words of wisdom out there? The conversation has just left me feeling like a bad person in general.

EDIT: TL;DR - Not wanting kids of my own means I can't want to help families. And I'm a bad person.
