My boyfriends parents broke us up. I want answers from mothers.?

Okay. We've been dating about 10 months. And I got scared I could be pregnant from him me, with *** on his fingers. So I called my mom, she told my stepdad, he told my boyfriend Devon's parents. We're 15.. which is normal for our age. Anyways his mom told me that we're over and I can never see him again. She then called me 5 hours later.. a little nicer about it. She usually gives into punishments and will completely change the punishment, to a lot less crappy.. do you think she might do it in this case? I've never known her to stick to a punishment. Thanks :)
