It's a p-sub. If he is looking at a woman sexually dressed/half naked/in lingerie etc. It's a p-sub. He is looking for ways to keep his addiction. My husband in the beginning thought instagram lingerie girls weren't porn because his definition of porn was "two naked people having sex".... anyways. He is not getting in recovery. You have every right to set boundaries to keep you safe. If you don't want a relationship with a man who is not faithful you have every right to set that line. It then falls on him whether he wants to cheat and thus have the relationship fail, or get into recovery and try to rebuild. Also sex is NOT a need. Water is a need, food is a need..... sex... not a need. Intimacy is a need. So the whole, "you don't have enough sex with me" is NOT a reason, you are not to blame for his addiction and his choices. He had the choice to come to you and say, "I would really love it if we could be more intimate" (define intimate in whatever way you choose -sex, cuddles, kisses, etc.) I am sorry if you have felt blamed at all, but you are not to blame. At this point, take care of yourself, set boundaries and consequences and try to work on communication (but that only works if both parties are willing). We are all here to support you!
