Did I do the right thing? PLEASE READ?

Approximately 2 months ago, I broke up with my boyfriend of almost 2 years. I am 15, he is 16. I broke up with him because he was very possessive and controlling. For example, he would never stop calling or texting me, he gave me extravagant gifts (with strings attached if you know what I mean), and he was had a bad attitude, and got mad at me if I wanted to hang out with my friends. This one time I was at his friend's house with him and my other friend and my mom came to pick me up and he kept persisting my mom and my mom got really annoyed about it. He would like say things like oh I want to be with your forever and he would actually make plans to get married! I couldn't take it! And at the school dances he would just sit to the side and not let me dance! I was miserable with him! NO ONE I knew liked him.They though I deserved better. The best part is, he would expect me to be all sweet to him when he was being mean to me! And he would act like the victim because I would get so fed up with and his controlling self and I would start saying how I really felt and he would cry like a freaking baby. LIKE I WAS THE BAD GUY! Sorry this is long but pleasee answer. I broke up with him and he was crushed and I had to change my number because every time I would turn on my phone, i had like 60 messages from him. Like he would say "Oh Melina, I will try for you forever you the are one." or "You will regret this." I had NO life whatsoever when I was with him! I could barely do my homework or study because I always had to put HIM FIRST! It has only been like 2 months and he already got another girlfriend who has a boyfriend! It really pisses me off because he thinks he can win any girl he wants. I hate to admit it though but ever since he said he got another girlfriend, i feel sort of jealous. But the thing was I was soooo happy to get rid of him everyone noticed i seemed happier and i even started hanging out with my friends again. He just wanted such a serious relationship i wasn't ready for. The worst part is he sends me messages that say i love you and i never wanted to loose you. I mean I can't even think about getting another boyfriend i'm scared now. I apologize for this being so long and please no rude answers! THANK YOU!
