Is it normal if i feel bad for my ex but wish him the best?

My ex and I had a great relationship. He was my first bf and as my first one, I thank him for being a great one. I love him for it and I love him as a person and a friend. We still keep in touch but note, it took a drastic amount of effort for us to finally be cordial. We broke up twice and finally the sec time, that was it. But I know something that is going to be hard for him and no I am not being full of myself, I'm actually being empathetic. It's going to be very hard for him to find someone else better than me. Not because I was good to him, but cause he loves me. He loved me when we were going out, I was his "precious" and he still calls me that or reminds me how special I was to him. He will always feel comfortable with me even now. He told me about some girls he's been dating and he hasn't had the greatest experiences. He won't directly tell me but he hints that he compares them to me since I was his first love. I feel kind of sad for him because I know where he's coming from. My current bf is my first love and I feel the same way as my ex; I don't think no one can come close to him if we were to separate. I would never want to make someone feel the way my bf makes me feel. Then I remember, oh wait, I already have. My bf is seriously the love of my life, or at least I feel that way at the moment. This is prob how my ex felt and when we broke up, he took it very hard like his whole life shattered to pieces. He confessed he did go through a depressing time and his family didn't know what to do since he was so reserved. But he's definitely doing better now on his own but I only feel bad for him when it comes to dating cause he will always compare every girl to me just like I compare every guy to my bf. As for me, I hope my bf and I do make it but if we don't, I guess I'm preparing myself mentally and emotionally to not go through what my ex is going through.
