Being a former military wife was tough on my friendships. It was even worst once we retired. In all honesty it was depressing. Upon retirement we returned to life as civilians. Major loss for me and more than likely for my husband too! The point I'm making is at certain junctions in life friendships can be brief and finding new friends can be a bit challenging.
Here are a few things I've learned on my midlife journey: (1) It's okay to spend some of this down time getting to know the new you. (2) By understanding yourself during midlife you will have a clearer picture of the type of people you desire to build new friendships with. (3) In addition, you will know the type of things you would like to do with your friends as well. Keep in mind, that during midlife transition your life will look much different than before you entered this stage and it takes time to adjust, so don't be so hard on yourself. New Friendships will Emerge with the New You!
