Starting to feel like I won’t change

This is rly my first time fighting back cs having sex wit my girl made me stop watching porn cs it felt wrong. But now we went back to saving that for marriage. The porn came back and it again still feels very wrong when I watch it. I’m trying to change and be more disciplined for God and my girl but it’s tougher than I thought. Every time I pass a day the temptations and curiosities get stronger 🫤
