If your struggling with lust or temptation in general, even if you truly want get out of that cycle, desperate to get out but still fall back into that same sinner and over again feeling like "I know I'll just fall back into the same sin again" being free for a week and sinning again and that sparks more sins. There is a way. A young monk approached a desert father and asked pray for me I am being overcome by lust. He asked him over and over again. The desert father saw that a spirit of lust was beside him, and an angel to help him was getting angry with how he handled his intrusive thoughts. That he didn't fall down before God. He told the monk it is you who are consenting to these thoughts. Then he taught him how to combat the thoughts and the monk found rest. His heart was in the right place but still, he sinned. Even when we don't feel it we are consenting to these thoughts, taking pleasure in them. We need to do something else to think about another thing and to not consent to them. Dontput yourself in a situation where you know you'll get tempted. Pray the Jesus prayer: Lord Jesus Christ, Son of God, have mercy on me a sinner... I hope this will set you free, God bless.
