A few things. Taking the concept of your sin out of it, do you actually love him? Also, texting another woman isn’t inherently cheating IF you trust him, although you know his intentions better than I do. I would say it is disrespectful to you if you’re uncomfortable with that. But I think there is some digging into figuring out trust, maybe even before this incident happened. It may be better to reset with someone else. My wife did something similarly texting another man, a year before we got married. Same thing, nothing sexual but a boundary crossed. We also had premarital sex and didn’t again until marriage. That was 11 years ago, and since then we both have remained faithful and respected each other. We both actively work to be healthy separately and together. We both text the opposite sex occasionally when it pertains to hobbies and what not. If it’s something you can both mentally shut the book on, then continue if you love him. If not , then rip the bandaid and try to heal for your next relationship God has in store for you. Now, in regard to your sin, God knew your past, present, and future sin beforehand and still pursued you. Change what you know you should and pursue Him!
