If you have options (other women) in your life you wouldn't even entertain taking back a cheater and cucking yourself. Seriously, it's fine if you don't have anything going for you, but it's also your responsibility to change that. You don't have to be the kind of guy who has no other options than to crawl back to his cheating ex. How many hoops do you have to mentally jump through to even think this is a good idea? Where is your father, what does he think?
