I don't know anymore

So my bestfriend and I are very very close ( we are both girls ) we've been bestfriends for more than 10 years. Almost every boyfriend I have ever had have hit her up immediately after we break up. I usually her exes hit me up too but I never answer I just delete them. She dead ass had a whole ass conversation and even dated them as well. One of my exes actually made us stop talking for almost a month. I don't know what to do and if I should actually be bothered about it .
