No sympathy for period leak 😢

I just need to vent. I just had to drop my car off with at the dealership and I had major anxiety about being in the crowded waiting room. My period is really heavy today and I was super paranoid about leaking. After talking to the guy for a while, I went to the ladies room to find that I had bled through my tampon and through my pantyliner and through my panties. Thank goodness it hadn’t reached my jeans yet! My bf picked me up and was a little snippy with me and I started to cry. He asked why I was crying and I told him what happened. I expected him to be sweet and sympathetic. Instead he told me that was my problem and not his and that I should have been more prepared since I’m 40 and not 13 and to grow up. Am I seriously the only 40 year old this happens to?? How could I have been any more prepared?? I’m trying to chalk it up to him not knowing what the hell he’s talking about as a guy, but now I feel self conscious. And yes, I know he sounds like an ahole, but he’s bought me tampons before, so I don’t know what his problem was today. Ugh. I just want to get back in bed.
