long story short, after a night of partying for my friends 21st birthday, i ended up making out with, who i thought at the time was just his friend, the girl he was dating. i had known that they went out once or twice, but from the intel i gathered from asking around, they were nothing serious. obviously his pissed at me and just told me that he has no interest in being friends with me anymore. now he wasnt a super close friend, but one of the kids i hung out with more frequently due to my situation in life right now. this is obviously going to cause group dynamic problems and all that sorta highschool headache bullshit. nows heres my question: should i feel bad and responsible about this situation? because i dont and just feel if he doesnt want to be my friend over this then fine, im not going to beg and plea with him to stay my friend. i honestly believe that at this point in my life people are a dime a dozen and i know who my good friends are already. just looking for a place to get that outta my mind. thanks for any input.
