Is he fucked up, or is it me?

I have had this conversation with my boyfriend, 3 times. You know the one about having pics, attached to various profiles. As innocent as they may be, why does he feel the need to put his picture up. I am so fucking angry, especially after he promised me he would not do it again. I cannot see why someone who is in a committed relationship has their pics online, for any reason whatsoever. Blog spot, innocent site, whatever, it should not be there and I am fucking tired of it. Part of my problem lies in the distrust I show him, but hey, when you have a hunch, why not check into it. You have no idea how fucking mad I am and how much this has made me even more mad. I dare not bring up the topic of trust or attempt to feel out whether or not he is being faithful. I do trust him, but when I see this shit, it makes me wonder. Am I being stupid?
