breakup

Kaitlin
So my boyfriend and I broke up after about a year because I found out he's been doing drugs and lying about it, i broke up with him because once finding out the every time I asked him about drugs he was lying straight to my face I decided I couldn't trust him. After he told his parents that we had broken up they contacted me and asked what happened and I came to find out that he didn't tell them I broke up with him, he said he broke up with me because I was controlling. He felt like I was controlling because I didn't want him to do drugs and when I broke up with him he just said "fine I don't care I don't want you to control me" I feel like he's changed a lot reacently and that this isn't the person I fell in love with. This break up has been very hard for me because I still love him but I don't think I'll ever trust him again, he was my first and i feel like there's a hole in my heart now. Do you guys think I did the right thing? And what do you think his perspective on this is?
