Is this grooming?

Hey i might sound dumb but i just want to figure out what to call this. Is it grooming? Is it SA? abuse?. My ex was a terrible human being. When we were BOTH 16 we met through a mutal friend. He then asked her for my number and then began messaging me being really sweet and made me feel incredibly special. He asked me out on a date and i said yes. On that date he tried to get in my pants but i said no and he respected that. We texted for a while and he would tell me im the most beautiful woman in the entire world and so many other things along that line. Eventualy he asked me to be his girlfriend. I said yes. He didnt want anything posted on social media about our relationship and never made any effort to meet my family. Our first date after that i gave in and slept with him and gve him my virginity. After i did he kept stringing me on and telling me he loved me and that i was so beautiful but he never took me out, only to his place for sex. I would tell him i didnt like that, i wanted to go out on dates and do things that couples do other than sex. He would take me out once basically just to shut me up and continue having sex with me. He wouldnt hold my hand or show any affection in public. Turns out i wasnt the only girl he was sleeping with and doing this to ( i didnt know this). I would hate him and try and leave and then he would promise to change and reel me back in just to do the same thing over again. Turns out he never considered us dating and used that as a tactic to sIeep with girls. Hed gain our trust and then use us. I was a naive teenager and stayed for an entire year before he left his facebook open at our friends house, my friend snooped and saw messages with other women of him doing the same thing and there was a lot of explicit videos he was recieving from multiple women. I even got a call from a private number once telling me he was messaging her and calling me expendable. Turns out it was another mutual friend he was trying to do this to. I met someone else who didnt treat me like that and finally left for good. He truly fooled me in to thinking i loved him. Was that grooming? Even if he was the same age as me?
