Rudeness or sexual assault.?

When I was 14 and dating my ex boyfriend he would always touch/rub/squeeze my butt, thighs and boobs, and wouldn't stop even when I was begging him to. I said to him with a dead-serious face 'Stop doing that. It makes me extremely uncomfortable. When I day no, you have to stop.' He apologised while laughing and did it again later. I constantly felt pressured into being sexual with him, and I was not comfortable at all doing it. Several times he touched my vagina through my clothes and I had to kick him away. He would lie on top of me, put me in head locks, and after begging and begging for him to let me go he might eventually. He would force me to sit on his lap fully knowing I hated feeling his penis on my vagina and butt. He threatened to finger me and rape me all the time because I told him I didn't want to lose my virginity until I'm 20. He had been sexually active since very young. While texting he would send rape threats, maybe trying to seem sexy and dominant but only making me feel powerless and trapped. He loved seeing my eyes water when he put me in a headlock. I was very uncomfortable and scared through all of this.

Was this sexual assault, or just rudeness? I sure felt assaulted and violated. I feel like I need to know because I'm not sure, and I don't have anywhere else to ask. Everyone at my school called us the perfect couple, couple goals, etc etc.

It was extremely hard because no one had a clue that this was happening, and it happened daily.

Thank god it's over.
