My (25F) acquaintance (21M) made me so uncomfortable, was it assault?

I met this guy two months ago at a social club meeting that occurs once every week. we became friendly and he asked me to lunch and coffee twice and i agreed, but i never thought of it as a date or anything like that, it was always just platonic. Im new to town and i didn’t know anyone here, also he’s WAY too young for me, so i just hung out with him because i had nothing else to do.

he was only in town for his military service and was due to move back home (two hours away from here) soon, so at his last night at this social club, he wanted to walk with me to the location. he met me in front of my apartment, unexpectedly hugged me tight, and we walked there together. that night he was super touchy and it gave everyone the impression that we were together. he made me wear his jacket, and put his arm around me when we were sitting, and put it around my waist at one point. i didn’t do anything because we were both drinking and i didn’t want to embarrass him in front of his friends.

he then insisted to walk me home, and i kept saying that i want to take a taxi alone, but he insisted. he was drunk at this point so i told him to just go home but he refused. we walked to my apartment and he made me give him a tight hug in front of my door, he wouldn’t let go and we spent like 10 long minutes in a hug with him occasionally kissing my neck. then he asked me if he can have an apartment tour, i couldn’t say no so i told him fine but just stay in the kitchen and look inside (i live in a studio).

so when we got up he hugged me again and started kissing me on my cheek and forehead, and asked me to kiss him back. i did. he then tried to ask me to cuddle with him on the bed but i refused. so he sat down on the floor and told me to sit in his lap, and im not sure why, but i did, and he made me sit in his lap while facing him. he hugged me and kept getting closer to me and rubbing my back in that position until i got up forcefully.

then he stood up and hugged me again and was moaning and saying a lot of weird things that made me uncomfortable. when he finally asked me if he could kiss my lips, i said no, and insisted that he leaves. he said “i’ll kiss you next time” and eventually left. i felt so uncomfortable and disgusted with myself, like i wanted to tear and replace my skin.

the next time i saw him in public i felt really weird and lightheaded, like i was going to get a panic attack.

i basically allowed him to do it all, and none of it was really that sexual. was it assault?
