You may not have realized that communicating your feelings and concerns is your responsibility. It’s not your partner’s job to bring that out of you, but it is their job to not judge or shame you when you do it. I can’t tell you the number of people who hold the belief that when they find the “right” person, that person will instinctively tend to their feelings and thoughts, relieving them of having to communicate them. Such a partner may exist in movies and novels, but I’ve yet to see a healthy, happy relationship where both partners weren’t taking responsibility for their own communication.
