Dude, what the hell is wrong with you? Who told you all this crap?
Why should she be meaningless now? I guess I sort of understand....really, you WANT her to be meaningless to you.
But, if she meant nothing to you now, you and I wouldn't be friends. You would be to me a crappy person who is emotionally challenged and borderline cruel.
The truth of the matter is she that she is not "just one person". You chose her to be your life partner. You trusted her. You made human beings with her. She's big effing deal. All of our spouses are. That's why every single one of us is here. No matter what they've done, what they've said or what the future holds, they matter.
And we would be a bunch of a$$holes if we didn't still give a sh!t.
One day she will be there when the boys graduate. When the boys marry. She'll be with you when you meet your first grandkid. She will be there because it will be her grandchild too.
Because she's always going to be in your life and your future....that's why you are still fighting for your marriage CIPA. You'd rather share those times with her as her husband...not just the "boy's father."
All you have to do now is get ready to see the boys and come up with your best "damn, I'm a hot commodity, you want some of this? yeah you do" demeanor for the party Sunday.
