Again... Not every guy is like your guy. And you can only lie to people so long before the house of cards comes caving in and they figure it out. Then what? You have a bunch of sh*t drama with people you "didn't want to hurt" and ended up hurting them more. Face it. You're telling our OP that it's okay to lie to someone for the benefit of a clean break. That's manipulation.
You really remind me of Emily Dickinson in this case...and not in a good way. At all.
Honesty is not to make yourself look good. Honesty is for being MATURE about a situation and handling it in a way that BOTH PARTIES know for sure where they stand. By manipulating someone, you're making yourself feel good because you got off free without having to tell the person what you're really thinking. In turn, you're setting them up for direct failure in the future because you're denying them the opportunity to grow as human beings from the situation.
Life is all about trial and error- learning through pain. You date someone and you screw it up? If they're honest with you, then you know what you did wrong and can apply it to the next person to come along. If not, they're going to make the same mistake and get hurt more. So, while it may seem like the "right" thing to do to deceive someone into thinking it's not them, it's DEAD WRONG because you're not holding them accountable for what they did that pushed you to break up. In turn, you're denying them the chance to grow from the breakup. And as Ashley stated, you never know if the guy is going to hang around... Hell, look at me! I'm one of those hopeful guys who would wait for the person to sort themselves out. I waited on the man I love for 8 months... Granted, I talked to other men and went on dates to give other guys a chance, but when things didn't work with other guys, I still held onto hope that I could be the man I wanted to be with for so long. Yes, not everyone is like me, but not everyone is like your guy, either. You need to realize that and stop playing with people's hearts. Or else, you will seriously regret these games one day because you'll have nothing to show for it but a long line of lies and a shiton of guilt.
Have you ever heard of Asperger's?
By telling him the truth, yes, she'll hurt him, but next time, he'll definitely know what NOT to do in his next relationship. And if he doesn't learn, then he's just a jerk who will never change. Either way, if she doesn't give him a fighting chance to grow from this break up, she's automatically making his next relationship a failure.
No, if she wants to hurt him more in the long run, she'll lie to him. People can calmly express their emotions in a state such as this. We all don't have to make Jerry Springer outbursts. As long as she's honest and tells him straight up how it is (without throwing a chair at him in other words), she'll be fine. You can't just think about now, fearoflove. You need to think about what this is going to do to him in the long run. That goes for any guy that you manipulate like this... No offense, but it's true...
