me and my boyfriend were talking on the phone about a week ago(at like midnight) and we were talking about buying condoms. we weren't planning to have sex right away, we just want to have them for when we do. well 2 days later i was at his house and all of his family(mom,dad,sis) were just sitting around and we were all talking. well my boyfriend brought up that 2 of our friends were close to starting a relationship and his step-dad said "so they might have to go to walmart soon" and we knew that he knew something. so he threatened his sister with a pizza cutter(not very nice... she's 13) the next day and she said she was listening to our conversation and she told their step-dad but not their mom(very good thing) and she said she doesnt want him to do anything stupid. well we did go to walmart, but i only got some pictures off my digital camera and we didnt even buy condoms. he showed his sister and step-dad the receipt but we're not sure if they believe him. now its embarrassing when i go over there. what can i do to make this better?i was planning on talking to his sister about it so she wouldn't worry about her brother. but anything else i can do?sorry for the really long post.
