Needing help with trusting my wife

Me and my wife had an argument when we fasted before we got married where in myself i had to prune myself away from a lot of things and now have made me better as man. One being that me always wanting affection and love and sex made me feel like she didn’t want me at times and flesh made me seek likeness and love from other sources like commenting on women *** on topics like “white women dating black men” and whether they should or shouldn’t. I never DM’d a woman and never had sex with any woman I’ve commented on but my fiance. Also me and a guy were talking about fantasies because he has a podcast and he was talking about i needing to move over seas and have a get a white woman or a Latina woman, also lusting over SSBBW women and women that are bigger and thicken than her. Long story short, she needs to heal from it for a while and i got a lot of making up to do. But all in all, I’ve deleted *** and a lot of things to give me a lot of clarity and change me for the better and I’ve succeeded 🙌🏾🙌🏾

But the real question is this. Should a woman keep old text threads in their phone from their ex’s or sneaky links that were before you and start a clean slate and have no contact with them???? I feel as though being married, it’s always men that is ready for their shot and waiting on me to mess up so she can go back to being with the men that are in her threads or at her job?? It’s hard to keep trust with a woman that always think they are the prize and they think that can have anyone they want and always talk about the fancy cars and stuff they had but never reassures the man they are with???
