If you were dating someone for 10 years and they were sleeping with their ex the entire time of your relationship, but you just got engaged to them, would you want to know that they were cheating?

Long story short. I was dating someone for about 4 almost 5 years. While we were dating towards the end I had a feeling that they were seeing someone else or something was going on like we were going to break up. In October they broke up with me and they said that they still see themselves marrying me but they just needed time to figure out life for themselves. Fast forward to a few months later in February, you find out that they are dating a “friend” they swore was just a friend. A friend that you’ve been introduced to when you were still dating. Now you confront your ex saying they are just a liar and they don’t acknowledge that what’s going on.

Fast forward again to fall after the breakup. You start messaging your ex, first it’s to get closure then it leads to hooking up. Yes I know it’s wrong, they are still with the person they left you for. Yes. It’s cheating but you’re still in love with them so you’re desperately trying to keep a connection to them so you continue to hook up. This was in 2015. Now it’s 2024, your ex is still dating the person they started dating right after you broke up, you and that ex are still hooking up on the side. You meet their dog that they share with their new partner in NOVEMBER. and then they send you a message, a TEXT MESSAGE, Friday night saying hey we need to end things “I have a lot of love for you” but I need to mentally focus and the situation we are in isn’t working. And then cherry on top the next day you find out that they proposed to their partner that they have been cheating on for the last 10 years.

I know I’m at fault too. I’m stupid for thinking that the connection we had was ever going to be something more than it already was. Just sex. But if you were the fiancé in this scenario, would you want to know or should I just leave it alone.
