Your wife is emotionally disconnected from you. You can feel the enormous gap that is between you two. She's just not the same person that you married. All of the love and affection that you once felt strongly from her is now replaced with silence and space. You love her and you wish things could go back to the way they were. They can. If you are determined to make your marriage work you need to understand what you can do to pull your wife back to you. Overcoming the emotional distance will help rebuild the bond that was there the day you two were married.
When you start to feel that your wife is emotionally disconnected from you, you'll likely set out to talk to her about it. Why wouldn't you? After all, we all know that open and honest communication is at the heart of any strong and lasting marriage. However, if you approach her from a place of expectation it's very possible that she'll retreat even further into herself. No one wants to be pushed into talking about their feelings if they aren't ready to. Your wife may not even fully realize that she's become so emotionally disconnected from you. If it has happened over the course of a period of months or years, she may just view it as part of the process of settling into marriage.
You need to draw her out in your own way. You can begin doing that by talking to her more about general things including what's going on with her job or her life. Ask her questions and then listen carefully to the answers. Look for any clues in what she tells you. Sometimes a woman is experiencing so much stress with balancing everything in her life that her marriage begins to falter as a result of that.
Keep telling her how much you love her on a regular basis. If your wife has questioned your devotion to her in the past, that may be causing her to pull away from you. If she doesn't feel appreciated she'll start to withhold her feelings. No one wants to invest themselves emotionally in a relationship if they don't feel they're getting what they deserve in return. By focusing more on her feelings and what she needs from you, you'll ensure she will feel comfortable enough to start opening up to you again.
