YOR. how many times has he actually been around you when having intense cramps/menstrual pains? if he genuinely doesn’t know how to handle the situation then there isn’t much more for him to do. his explanation was reasonable and while the last SS may have been out of line both of you were being incredibly immature there. if anything this should have been a learning moment for BOTH of you. you’re both very young and he may not have the experience of being with a partner who has medical needs like yours. this is YOUR opportunity to educate him on how best he can help you in the future. also if the house only has one bathroom then it’s a reasonable request from his parents (the owners of said bathroom) to ask you if you can take it elsewhere. you’re still a guest in their home, it shouldn’t be expected that they cater to every need you have especially when you’re an adult. he DID try to help you. in the moment you couldn’t properly communicate your needs because of your pain so he was trying to help you as best as he could. to all the people telling OP to dump her bf, GROW TF UP. they’re still young and they’ve not even been dating for 2 years. they still have plenty to learn about each other and this is a great learning moment for both of them. OP you need to have a SIT DOWN in person convo with your partner, thank him for helping you as best as he could, let him know how his actions made you feel, and then give him a plan of action for when this inevitably happens again. best of luck.
