disgusted

i found several blonde hairs in my room and on my bed. my hair is dark brown. my bf broke up with me a few days ago but before we broke up i remember finding the same blonde hair in my kitchen and asked him about it. found that this girl was his 2nd best friend on snapchat and i told him to stop snapping her which he did until he broke up with me and now im finding hairs in my room. we love together and this is so aweful to go through i confronted him about the hair and he just denied it all
