Am I bad friend for not believing her rape allegations?

Anonymous
My closest friend and I have been best friends since birth and we are both in our 20s.

My best friend has gone through 4 long-term relationships in the last 8 years. 2 of those relationships were completely online from across the other side of the country (never met in person). When she lost her virginity in her first relationship, she confided in me and said it felt so good and that I needed to try it for myself soon. She constantly bragged about how good her sex life was in her relationships and how she would have sex every day. But I began to notice a pattern..

Everytime she starts a new relationship, she tells me that at some point during her most recent relationship, she was raped or sexually assaulted by that ex. Every single time.

As her best friend and from one woman to another, I want to full-heartedly believe her about all of these allegations , but she does have a tendency of lying and I can't help but to think these are just more lies to put down her exes. Especially with 2 relationships being completely online, I'm not sure how it's possible to sexually assault someone. In my heart I feel a lot of guilt for not fully believing her, but I would never openly admit that to her. I offer my 100% support to her regardless.

Am I wrong for deep down inside not believing her about something so serious?
