There's no point to regret when it happens and there's no point to find solutions to solve the problem you are facing.
You've got to let time passes that's the only way you'll get out of it and start a new life.
When you are single it's easy to left it all behind you but when you're with children that's a good thing to let your mind have a great spin.
Reality is not easy when you've made your sacrifices but you doesn't get anything in return that's the time for you to stop putting so much effort into it. Seriously!!!
Enough is enough.
If staying hurts so much leaving is the best choice but leave it in an appropriate way.
YOLO !!!
Think carefully when you have the chance because there is no reason for you to be regretting afterwards.
