Really sorry you find yourself here. Lots of relationships survive a partner sleeping with someone else, even if there is an emotional bond too. Around 65% of affairs end within 6 months (once that swept away 'in lurve' feeling reduces). Also, only around 3-5% of people who had affairs marry the AP, and of those around 75% end in divorce.
Contrast this with around 70% of relationships which survive affairs. I'm not saying it is easy - I'm certainly not finding it easy at the moment. But can you compete - Heck yes!
So, it is early days. Don't lose heart. Heed the advice from others on this forum, which is a lifesaver. Get working on yourself and your ability to detach and GAL (for the sake of your sanity and self respect.)...
Hang on in there, and very best of luck to you!
