A few months back I was looking at my boyfriends reddit account and stumbled across a thread where he admitted to being attracted to younger kids. He explained he would never act on any of those urges or feelings because it makes him feel dirty and disgusting. He suffers from anxiety and depression for a few reasons unrelated to that, and now I'm realizing that this is probably a contributing factor as well.
We have an extremely strong and loving relationship. I want nothing more for him than to feel at ease about his situation. At first I was terrified for a lot of reasons. But I've let this information sink in for about 4-5 months now and I've done research about what can be done. I feel way less freaked out and now all I want to do is help him.
I really want to bring this up to him, to tell him I support him and love him and want to help him get better. But since this isn't something he's actually confided in me, I feel like bringing it up would make him feel scared and attacked. I don't want to corner him into talking about this, but I want him to feel comforted knowing I won't leave him or think he's disgusting. All I want is for him to feel better.
How can I bring this up to him in a way where he won't feel attacked?
