This time must be regular, like at least once a week, and there should be no excuses for failing to make it. Work, guys nights out, girls nights out, sport and all these other things have an important place to play in both your lives.
But if you want to fix a broken relationship, then you will need to work at it..and with sufficient commitment that when you commit to quiet time between just the two of you that you both fulfill the agreement.
Step 2-Go on Dates
Organize regular dates, just like the old days, with some time apart before the date to create a frisson of excitement like the old days.
Step 3-Prioritize
If you want to fix a broken relationship you will both need to recognize the problem and commit to finding a solution..no matter how busy work is or any other distraction. You need to see putting your relationship back on track as the number 1 priority in your lives for now. Because if you don't the pattern of behavior which has led to the fracture will become habit and reinforced and become even more difficult to change.
Step 4-Forgive
You will need to forgive your partner's failings when he/she is prepared to recognize them and commits to rectifying the situation. Carrying a grudge is a lonely job and will not help your relationship. This is not a one way street and hopefully your partner will take the same attitude and recognize that "hey I am not perfect, but I am sorry".
Step 5-Recognize the differences between men and women and celebrate them..don't let them be a barrier to a loving relationship with someone who was your best friend not so many years ago.
