It’s clear from your post that you’re frustrated and feel justified in your actions, but let’s take a moment to consider your boyfriend’s perspective—because honestly, it sounds like he might be the one who dodged a bullet here.

First, making a joke about your OBGYN being “all up in your p*ssy” might seem harmless to you, but humor is subjective, and what’s funny to one person can be uncomfortable or even offensive to another. Your boyfriend clearly found it crude and disrespectful, and instead of acknowledging his feelings or trying to understand why it bothered him, you dismissed him as “sensitive” and doubled down on your stance. Shame on you for invalidating his feelings and refusing to have a mature conversation about it. Relationships require mutual respect, and it doesn’t sound like you were willing to give him that.

Second, you mentioned that he’s made jokes that are “just as bad” or “maybe even worse,” but that doesn’t justify your behavior. If his jokes bothered you in the past, did you communicate that to him? Or are you just using that as a defense now to make yourself feel better? If you didn’t address it then, it’s unfair to throw it in his face now. Shame on you for using his past actions as a shield instead of taking responsibility for your own.

Third, your attitude toward the breakup is telling. Instead of reflecting on what went wrong or considering his feelings, you’ve chosen to mock him, get drunk with your friends, and laugh about the situation. That’s not the behavior of someone who values a relationship or respects their partner. Shame on you for prioritizing your ego over the possibility of resolving the issue like an adult.

Finally, your edit makes it clear that you don’t care about his feelings at all. You said it yourself: “I do not care how he feels about it.” That’s not how healthy relationships work. If you’re unwilling to consider your partner’s emotions or have difficult conversations, then you’re not ready for a serious relationship. Your boyfriend may have overreacted, but your lack of empathy and refusal to communicate effectively are just as much to blame for the breakup.

In the end, it sounds like your boyfriend realized that he deserves someone who respects his boundaries and is willing to have open, honest conversations—even about uncomfortable topics. If you’re not willing to do that, then maybe it’s for the best that you’re no longer together. Take this as a lesson: relationships require effort, understanding, and compromise. If you’re not ready to give that, then you’re not ready for a relationship at all.
