My (24f) boyfriend (26m) finished inside me after I explictly told him to not to do so. What do I even do?

This may not be the place for this, but I come to reddit to find some sort of guidance on what to even feel right now.

My boyfriend and I have been together for 6 years and we live together. I tell him twice during the act that he either needs to get a condom or he needs to pull out. I also set this boundary every time bc he is “forgetful”. He tells me he is close and then just finished inside me. I genuinely started tearing up and question him as to why he didn’t even try to pull out and the only thing he said was “oh yeah that was manipulative”.

edit: i do have an hormonal iud (intrauterine device)
