Friends

My bf came to my country to visit me.He wanted me to get boarded as it’s easy for him to visit me rather than me being in my parents house. I went to a private apartment with my two friends(S,X). So first day he came my friends were sleeping. My bf came to my room n stayed. We wanted to go out. By that time my friends were up. we gave then some chocolates and headed out. After one hour my friends mother has called my mom and said that a guy came to the apartment. so my bf during that time was assuming that my two friends probably told the warden. I was angry at my friends. I asked then whether they were the ones who told it. But they said it was a man who lives in the 2nd floor who checks his cctv. I went to my room for a bit. During that time one of my friend(S) has called their mother and told all the details of my relationship to their mother. and said that i came to the apartment to meet him as in. Me being oblivious about all these cooled down n apologized to my friends. We even shared dinner That night. My mother came the next day n apologized to them as well. I went home. After a few days I realized that my friend(S) has removed me and my other friend (M) from her close friends *** acc. After the holiday when we met she completed ignored me, and talked to other. During lunch break I asked my friends whether it’s okay to eat in class, for which that friend(S) frowned at me and said she doesn’t wanna eat. Even in the canteen she sits faraway from me. My friend group had 5 members me,M,S,X,D. After that incident S , with X and D has put the same wallpapers, funny names excluding M and me. i Feel really bad and hurt by this situation. How do I cope up with this?
