Soo my brother dated this girl(Alexa) for like a year and they broke up almost two years ago, they are both 4 years older than me (i’m 15 and they’re 19) anyway.. me and Alexa became reallly close friends when they were dating and then he broke up with her but my brother and i were both still friends with her. then we found out that she had cheated on him while they were dating so he naturally got really mad and they stopped being friends but i was still friends with her. he started dating this other girl(emily) and she was nice at least at first, and i was hanging out with Alexa a lot, which emily didn’t like. when my brother and emily has been dating for a while she started to get a bit crazy and jealous of alexa and thought my brother still liked her and was still talking to her and then one night me my brother and emily went to the cinema together and when we got there we saw alexa and i went to say hi to her and my brother and emily just went straight to the line. when we got home emily was really mad because of alexa and broke up with my brother(for a few days). they didn’t talk for like 3 days and my brother asked me to stop being friends with alexa and block her on all social media.(my brother is my best friend, we are very close) he told me that ever since they broke up he didn’t like that we were friends, so i blocked her. this all happened in march 2018 and i’ve seen her a couple of times since like in the store and the mall but we haven’t talked or said hi or anything. and lately i’ve been missing her so much and i don’t know what to do so i need advice. i mean i can’t just unblock her and tell her i’m sorry now, can i?
