Trigger warning!!! I think i was date raped?

Soo i dont really know what to think of this..things have been really off the last few days...i have somethings going on in my life and ive been kinda reckless ill admit but still conscious of the decisions ive made.....but im trying to process recent events..ive tried to let it go but something just isnt sitting right with me... and i feel like i might of been date raped but im having a hard time with it all..

So a few weeks ago i went out with a guy we just went to a local bar. We ordered two pitchers of long islands but the pitchers were honestly really small enough just for both our cups so we each only had two drinks and a shot of crown apple (i also had less poured in my cups both times and never walked away from them)... thing is i know ive drank waaay more than that and have been able to tolerate it. The last thing I remember is saying i was ready to go (we drove separate cars) at some point i guess we ended up in my car though (i parked right in the front of the building) i dont know if he drove it or i did but we ended up behind the buildings (its a shopping plaza) from there i dont really remember much from that point. Just in a out..i woke up the next morning in my bed so apparently i drove home and that scares me bc i don’t remember none of the drive..i had some scratches and cuts on my arm and knee as well as a long cut right along my vulva and very sore in that area...and when i was about to leave the house the next morning i realized my tire was completely flat but there was a hole in it..i messaged him and asked what happened and if we had sex and he said he doesnt know he said i gave him head but i dont even remember that..i kinda just played it off and just acted like it didnt really happen and changed the subject (havent talked to him in a few days now tho) ....its been a week and i still feel “hungover” and just over all sluggish. I think mentally ive been trying to suppress it but physically i feel like i cant shake it. There was no other damage to the car so I assumed i hit a curve pretty bad...i dont know what i want out of expressing this but i guess to just understand it. Like i said ive never been that drunk ive blacked out but like once i got home and went to sleep i can usually remember things the next day. Ive also cut back on drinking to that point since i have kids (who btw was with their dad). This is the first time im actually expressing this i havent even said anything to my friends.
