I'm with Collin on this. I use to have the naive thought that two people could reconnect and be happy again. I've since trashed that flawed concept. Partly because I just learned it the hard way. But logic out weighs 100% of the time. Sure you might get her back again for a SHORT period of time, but those issues will always be there and those initial feelings of attraction and blind desire are gone.
If you get her back, you won't be yourself. You'll be very calculated and over do everything to try and impress her or avoid any arguments. It will make you appear needy which means she will lose attraction in you.
It doesn't work. Sure the devil you know is better than the devil you don't, but it won't be a lasting reconnection.
