I and my boyfriend had been together for over three years till I broke up with him three months ago. It was a fine relationship and I was quite happy the entire time. However soon after our third anniversary something just felt wrong and I ended it knowing he would be hurt. I have now met a man and there's a spark between us and I find him irresistible. But I'm still friends with my ex and I still love him a lot and want him to be happy. Even though he seems quite happy I know he's not. I now want to fully move on but I am worried about my ex getting hurt because he tends to be erratic when depressed. Please help me for I'm worried I'm still attached to my ex. I'm 21.
