Is he really addicted?

To question such an addiction could be rather offensive to some. So, before I really get into what it is that I've been thinking about, I want to apologize for any generalizations or even over-simplifying statements that may be made in this post. It's an online community so I'm looking for answers from someone or people who is/are knowledgeable about it.

I have a boyfriend who claims he is addicted to porn. Upon hearing this, it makes absolutely no difference to me; I love him and want to be with him regardless. I have no interest in leaving him for something that I really only question the validity of his case and whether or not I would call it an addiction.

Now, I'm a newbie to all this. I have heard of porn addiction and watched a few tidbits on it in the past but it's not something I regularly keep up with hence seeking out answers on this online community. It obviously seems like something very serious and causes lifetime impact. My concern for this is not really about a strain in my relationship with my sweetie pie, but more for his personal well being. I want him to really consider whether or not he has an addiction; his perspective on it now seems damaging and I don't want him to continue seeing himself in this way if there is truly nothing to concern himself over.

My boyfriend spends a lot of time on the internet yes but doing educational research. I read on a few sites that even just spending a lot of time on the internet is a sign of a porn addiction, is this true? Additionally, my boyfriend has never spent increasing amounts of time alone, and doesn't prefer to be alone in social situations. He doesn't spend money on porn, he's not critical of my body (at least if he is I'm not aware of it), doesn't have a hard time becoming aroused with me, we don't have sex that frequently and it doesn't pose a strain on us, and has not had a change in behavior. He is emotionally distant but this has been happening for 3 to 4 months now and I believe it has nothing to do with this.

I'm having a hard time really considering that the situation he's going through is even something to worry about...I don't want him to worry. I want him to be at peace. Does this make sense? I don't want to question him on what he thinks is going on with himself--after all "no one knows you better than you". I guess, I'm looking for some clarity on what constitutes a porn addiction and how I can be supportive through his journey to recovery, since right now, I don't feel like I'm doing a very good job of it. I find myself at a loss of words and he's okay with it because it's something "he needs to figure out on his own". Yet, I want to be supportive of my boyfriend and want to maintain our relationship. I'm so lucky to have him and if what he really has is an addiction, I want to move on from with with him, together.
