Well, then quit being superman! Are you doing all those things to win love? to get her attention? What I am saying is you do all those things and I bet she doesn't even realize what you are doing. So, stop doing it. Let her start doing for herself, let her take care of her vehicle maintenance, let her make the budget and pay her bills, don't save her from herself. Let her miss you. Is that a 180?
How did it help last year to make 2/14 special? Treat yourself, the kids, the dog (do you have a dog?) Believe me, I know how hard it is and how much it hurts to ignore and be ignored on Valentines Day, wedding anniversaries, even Christmas. But if what you've done in the past hasn't worked then it's time to change what you do in the future. You know what I do for ME now on VD? I take my mom for lunch. I still share my love with someone special in my life.
You seem stifled right now, focusing too much on W. Look in the mirror, focus on the guy you see there.
Live your life while you are still living. Riding the trail less traveled.
