Confused

A few months ago my fiancé (boyfriend at the time) confessed to looking at pictures of women online, but said he had stopped a while ago. Up till then we'd had a basically perfect relationship, and a fantastic sex life, apart from being long distance in University holidays. After his confession I immediately asked a plethora of questions about his habits, and was not convinced by his answers. He had always been reluctant to talk about masturbation, despite my openness about doing it myself, and when telling me that these pictures were very rare and never videos and "what's the point of me lying when I'm confessing everything"... I wasn't buying it. My fiancé has always been prone to little lies, and being quite fake in front of his friends. He claims to have never been happy with himself as a person. A few months of paranoia and self doubt combined with much interrogation on my part ensued. During these months we had countless conversations about the "pictures" and I even started thinking I might need to go to a counsellor to deal with my "trust issues", so many lies were told in this time! All of this pain and evident corrosion of my wellbeing was still not enough to make my partner confess. In this period he proposed, and a few weeks after claimed he had to tell me the full story so he could propose with a clear conscience. However, his conscience was far from clear. I recently discovered the cold, calculated viewing of women purely to "exploit the fact they'd give (him) an erection" was far from the truth. He had a full blown porn addiction. I found teen pictures, snapchat pictures, videos and searches for free webcam sex (of which he looked at some websites). The only thing that held true, and this is the reason I didn't leave, is that there was absolutely no evidence of this happening after his initial confession. I also noticed signs of him seeming happier with himself as a person and wanting to live healthier over the past few months, and it was hard for me to understand why, but recovering from a porn addiction would explain it. I find it very hard to understand that he wasn't choosing these photos instead of me. He claims he never clicked on a web chat, but the way this addiction escalates, I don't see how that can be true. He would do this 2 minutes on average after we finished Skyping, yet claims he wasn't aware he was going to do so when finishing the conversation with me, can this actually be true? And can a person really look at pictures and images without comparing them to the person he is with? And does he really think I'm more beautiful? Since the trauma of finding out his search history I get triggered by anything that reminds me and have a flurry of emotions overcome me. I'm finding this especially hard to deal with when the one person I need right now feels terrible about how miserable I get, and could well still be lying. If he continues to lie, I will never recover. We've started counselling but I'm wondering if for my own sake I should get out now, before the next batch of deceit breaks me beyond repair.
