NO, I don’t think that speaking to your exes four or five times a week is normal or acceptable.
Yes, you have to keep in mind that they are exes for a reason but it’s understandable you feel insecure when she’s talking to them nearly every day.
Maybe she is secure in the knowledge that they are “just friends”, but she has to understand how it affects you. Why not ask if she’s OK with you talking to your exes five times a week? I bet the answer is “No”.
Maybe she hasn’t thought about it from your side of things but she should if she’s serious about your relationship. You need to find a compromise.
