is this rape or is it my fault

so i was drinking quite heavily last night, didnt get blackout drunk but i was very out of it by the time i was trying to sleep. my brothers friend comes in my room to sleep in my bed with me, knowing i have a boyfriend, but im too drunk to really do anything about it. i dont remember much but while i was in that state of half-sleeping-half-awake drunkenness, he started feeling me up and fingering me. i didnt give consent but i was too drunk and tired to tell him to stop
