How do I make it upto him?

the best thing you can do is simply apologise, explain to him that you are simple human and that we all make mistakes big o small from time to time. let him know that you know that what you did was wrong and you know now not to do it again. Speak to his friends and apologise to them and explain how you were the one at fault and that you had no reason to go and tell them and that you would prefer it if they would reconsider what they think abput your boyfriend, that is if what your boyfriend did was just a normal thing, if he hit you or anything like that I would really reconsider doing anything, Let your boyfriend know that you are there and waiting for when he is ready to talk. everybody needs a bit os space when theyve been hurt by somebody. give him a couple of days to come around if he loves you he will forgive you. if you cant get him to talk to you then write him a letter, dont make it complicated or to long, just nice and simle and honest, he will respect that, Hope all goes well and let us know how it all gets on ! :) good luck!
