You doing things like giving her that card and calling her just reminds her over and over how she DOESN'T feel about you. It's a very bad feeling, and you're shoving it in her face. Leave her alone!
You are still in this game. She's saying things to you my W was telling me 2-3 years ago. I thought I just needed to be a better H, be more romantic, do more around the house, etc. WRONG! The more I did, the farther away she got. She's telling you what she needs. She needs you to get out of her face. She needs to feel like loving you is a choice for her, not an obligation, and showing her that it's a choice for you too is exactly where you have to get. What you're showing her is complete and utter DEPENDENCE. Coach's suggestions are dead on right. When your W feels like you don't NEED her anymore, then she maybe she can relax and evaluate how she really feels. Until then, she'll keep her protective walls up.
