My Sister Confessed!!

So last night my younger sister told me she NEVER uses protection when she sleeps with the guys she dates ( which is so many)!!! I could have lost my whole mind! I asked her what she would do if she were to get pregnant and she said. " I'd probably just give it to you". This statement shut me down immediately. I yelled at her " YOUR NOT TRYING TO  GET PREGNANT FOR ME RIGHT???" And she scuffs " of course  not but I couldn't take care of it, so I'd just give it to you". Well then I was mad again. Obviously I yelled at her for a good 20 minutes about how reckless she was being. But the whole rest of the night. I wondered if maybe it was because of me. She knows I want a baby. God I hope she starts using protection, yes I want a baby but absolutely not like that. Sorry guys just had to vent. Can't tell my SO because he thinks of her as a sister too and he would lose his shit.
