Tips- try to eliminate these two words from your marriage. "Never and Always".
"You always complain about that but you never...." "You never offer to take the twins, instead you always..."
You get the idea. Instead of these words try; "When you do ...., it makes me feel ....., in the future would you please....." Let your spouse know you appreciate their help and contribution. Try not to start off your sentence with 'You' use 'When' instead.
Make it a point to appreciate every little thing you both do to help each other.
Stop blaming. Instead of telling your spouse "You rarely hold my hand at the movies anymore." Try rewording it by saying something like; "I'd like to hold your hand when we are seated in the movie theater; it reminds me of when we were dating." When your spouse compliments your appearance respond by saying with a smile; "Thanks for noticing, I appreciate that." You'll get more of what you want by saying it in a non attacking way. Try it!
When you walk down the hallway, or are walking in opposite directions, do you acknowledge one another with eye contact, a smile or a kiss? Some couples walk past each other without even looking at each other like they are trying to avoid them. Or maybe an urgent task is far more important than they are. Sometimes we get so busy, we do this when we don't really mean it. Take every moment in your life to appreciate each others presence. The eyes are the window to a persons soul. If you passed a neighbor or someone you knew, you would stop and acknowledge their presence. Your spouse should be that way too! Every day, every moment. Show each other how blessed you are to have them in your life. Your children as well.
