i had this best friend that dated my brother and she cheated on my brother and me and my brother are very close so i stopped being friends with her and i blocked her on social media(my brother asked me to). this was almost a year ago. i’ve seen her a couple times since but we haven’t talked. now i have been missing her so much and i just unblocked her on facebook 2 min ago but should i add her as a friend again? and should i talk to her? or do you think she’ll ask about it if i add her? i don’t want my bro to find out tho!! what to do?
