Broke a 75 Day Streak. I feel so defeated

I broke my 75 day streak today. While I’m determined to keep on going, I still feel really depressed about it. I’m very proud of myself that I made it 75 days, but I still feel like I’ve yet again failed my boyfriend. I told my partner about my relapse, and I feel like a failure. He is reasonably upset, and I feel like I just continue to hurt him. We’ve had some struggles relating to pornography before. I don’t want to keep hurting him. Should we break up so he doesn’t get hurt? Does anyone else feel this way? I’m starting some therapy next week, wish it came sooner.
