Sometimes get so sad thinking how every man in Stephanie's life has either betrayed her, abused her, used her, or let her down. Her Dad abusing her and her Mom. Her babysitter attempting to sexually assault her, her dad teling her she was lying when she told him, this being the moment she first decided she could rely only on herself, that she can't expect others to help her.
Being afraid of men for a time after that, quitting her piano lessons because she was afraid the piano teacher would hurt her, having to overcome that fear on her own, no therapy or support to help her.
Her gymnastics teacher, a man she trusted so much she got angry at her Mom for pointing out his suspicious behavior, turning out to be a drug dealer who sold to his own students.
Dean abandoning her when she wanted to stay and help with the earthquake. Already knowing that he wouldn't want to help her with the baby when she realized she was pregnant. Being proven right when he finally comes to see her, asks if the baby was his, and then rather than asking anything else about it, is pleased she gave the baby up for adoption because that means they can get back together, obviously.
Tim being someone she can trust to help her and have her back, but someone who rooted out her secret identity against her will, and after knowing it, does not take it seriously: shows he can't be trusted with it by calling her by her name in front of actual criminals, introducing her by name to other heroes without her permission. Not apologizing when Steph calls him on it. Meanwhile he guards his identity and Batman's so seriously he doesn't tell her his name even when they start dating. Still, he's the "nicest guy she ever dated" and "too good for her" in her view.
(This is not Tim bashing, okay, he was just objectively very wrong to do this. It could have gotten Steph killed!)
Batman, the man she used to hope to see in the sky when she was a little girl, who she considered her savior whenever he put her dad away, dismissing her. Batman dangling acceptance for her and then vanishing, only to come back and fire her for no reason. Punishing her for trusting him. Accepting her as Robin, but her knowing all along he was partly using her, him constantly making it clear he favored Tim and comparing her to him negatively, him putting her on probation and not trusting her with his identity when he trusted every other Robin, firing her for disobeying an order once (out of concern for him!) despite the fact she had been performing so well until then.
Black Mask torturing her while saying any vile misogynist thing he could think of. Overtly sexual things. There was no way she didn't think of her babysitter, didn't feel afraid.
How, coincidentally or not, things started looking up for her as Batgirl because she carved out a space where a man's support and approval wasn't necessary. She worked with Babs, who supplied her with weapons and help, who was willing to have her back even when Dick and Damian disapproved. She no longer needed Tim to be willing to work with her (something that she did have to rely on in her Spoiler days pre-Batman-acceptance, because he was the only one with actual training who was available to teach her things she needed to know (like dressing bullet wounds), the only person who gave her any backup, and the only person who supplied her with weapons). She made it very clear she didn't need Bruce's approval either.
(There are exceptions ofc--there's guys like Connor Hawke who were nice to her for the brief times she interacted with him, Reverend Knutland who was very sweet and supportive of her as Spoiler in the brief appearance he made, etc. It's more about a disturbing general pattern that seemed to pervade her story that became less catastrophic for her once she gained independence as Batgirl. It's also interestingly when she starts having some more chill relationships with guys too--Francisco, Nick Gage, etc--ones not marked by disapproval, drama, and mistrust so much).
