I found out my partner of many years fancied someone at work, they had been flirting over text I cracked up and put a stop to it, but it still continued, they couldn't stay away from each other, I love my partner and didn't want to lose her, I offered an open relationship as long as I didn't know anything but of course this didn't work, I kept changing my mind and calling it off telling her it was over between us but she just kept begging me to stay and putting an end to it. I feel like she misses the OW but she tells me she doesn't, what do I do now, I only want to make her happy we have been together years and I know we have a future together, does it make things interesting? I know it did and brought us closer, please give opinions, need help with this one
