After Divorce you need to end the previous chapter of your life and start a new one. After this you have to move on alone and this could alter your relationship with others. Some people might not need help in getting over their failed relationship. You should make sure you remain positive and close with all your friends and family members.
Handling your relationship with an ex-spouse is the hardest as seeing them in front of you can remind you of the whole matter. This is one of the first relationships one has to deal with after divorce. There might be children from your marriage and splitting up of the two parents disturbs the children's mind.
Make sure you speak kindly of the other parent as the children love both the parents equally. Make an effort to dissolve the past negative feelings concerned with your ex-spouse and try to get along with him/her. Don't leave a bad impression on the children about the other parent. This is the most complicated piece of your married life and you should think about the best interest of the children.
Post divorce, your relationship with some people might change. The family members of your ex spouse may not want to maintain any relationship with you. They are not your blood relatives so let them decide whether they want to keep the relationship with you or not. You can call them once in a while but be kind to them and don't try to push yourself on them.
Even your relationship with friends might change. Keep in mind that they are entitled to their own opinions and they might choose sides amongst both of you. This should not ruin your friendship with them. Accept their opinions and always remember that if they truly are your friends they will find time to spend with you.
Keep in mind that in the end, post divorce, your relationship with people is going to change. You have to work with your family and friends to gain the best relationship for all the people connected to this matter. After divorce, you should discuss the best interests of your children with your ex-spouse and remember that breaking up with your spouse doesn't mean that you have cut off all relationship with the friends and family involved. Don't take their choices to heart as they have their own views of life. Don't think anything less of yourself just because your relationship failed, there will be different people in your life and you should learn to develop these new relations in your life.
