If you're childfree by choice, do NOT feel sorry for a friend who found out they're infertile.

A few days ago, I learned that an old friend of mine found out that he's going to be infertile for the rest of his life. He's in his mid-twenties. He told me how sad, depressed, disappointed and angry he is about it, and he's even considered suicide. When he told me, I was surprised at how calm I was, and when I told him that I was also infertile, he reacted as if he felt better (I don't know why). I don't want to die, I'm actually happy to be childfree. He told me how sad it is that he won't become a father or have a family of his own, and how he'll miss out on the fatherhood experience. When I told him that I'm actually happy to be childfree and that I never wanted to be a parent, he looked at me as if I was insane. He tried to convince me to be sad about it, telling me it's a shame that I'll never become a parent, and that I'm being irrational. When I insisted that I don't want to be a parent, he told me that I was being selfish, and that I was letting my future family down. I told him that I'm not interested in marriage and that I don't want to have kids anyway, but he told me that I was being selfish for not wanting to have kids. He even told me I was being immature, infantile and irresponsible for not wanting to have kids. A few days later, he apologized, saying that he was projecting his negative thoughts onto me. I told him I forgave him and that there's no need to apologize, but I couldn't help but feel offended that he tried to shame me for my personal choice. I'm still happy that I'm infertile/childfree, and I don't regret it. I was actually relieved when I found out, because it felt like a burden had been lifted off my shoulders.<br><br>My question is, how do I deal with this situation? I have a very hard time forgiving people who try to shame me for my personal decisions, as I feel like they're attacking me on a deep level, and I don't know how to deal with that.
