My porn addiction has now ruined my relationship with my girlfriend. Some info, I've been looking at porn since I was about 13 and haven't stopped since. It got especially bad when I was living with a couple friends where I was single and left to my own devices and I fear I've damaged myself so bad I cannot be with anyone because of the problems I've faced in this relationship. My girlfriend and I have a child each from previous relationships and we just recently had a baby boy. I've been distant since before the baby was born and it was addressed that I had a problem and I would work on it. I failed to work it like we discussed and now two months after our son is born she is leaving me for lying to her about looking at bra less models on social media. She has refused to talk to me about this and any time I try to make amends she rejects it. I feel disgusting and ashamed of myself and very depressed. I need help and I don't want to lose my family but I fear it's already gone too far.
