AIO? My friend thinks my boyfriend raped me.

This weekend, my boyfriend(M21) and I(F19) went out drinking with friends including one of my closest friends and her boyfriend. I got drunk but I was aware of what was happening and still having fun. Later that night, my boyfriend and I had sex in his car near the bar. It was mutual.

The next day, I told that same friend about it, and she got really serious. She said she saw how out of it I was at the bar and that since he was sober, I couldn’t have given proper consent. She straight up told me she thinks it was rape. I remember saying yes, I felt safe, and we’ve been together for a while. I am bit mad and upset at my friend even if it was a place of concern. Am I overreacting for feeling this way?
