The issue is Poor Communication.
The ''my partner should read my mind'' and therefore figure out what I want, or how to make me happy, is a terrible mentality to harbour. First of all, your happiness is your responsibility, not your partners. So don't assume he/she would know or fix everything for you. Whether you're in a domestic partnership or marriage, without proper communication, your relationship will not thrive. If you and your partner struggle to communicate, you'll both struggle with everything else.
Poor communication has lead to the demise of many beautiful love story and potentially happy marriages, because one member or both couple lacks good communication skills. This leaves them fighting and arguing all the time, rather than growing to love each other more...
You need to understand; no one is a mind reader. It's wrong for anyone to assume that their partner should read their mind, and figure out what you want, without you having to tell them yourself. It's not ideal to live life, or manage relationship with this mentality. You don't leave your communication skills for others to figure out, because they're in a relationship with you. It's your responsibility to communicate your feeling, your thoughts, your ideas and your concerns to your partner, for a better understanding of your expectation or your worries.
In my book 6-Misconceptions-About-Marriage I have detailed this topic as the Number One Myth people have in relationship, which is also the number one reason couple are struggling. Because, If you can't talk about the issues, the other person won't know. If you don't discuss it, it can't be fixed. If your partner don't know about it, they're bound to keep making a mistake that you'll perceived as falling short of expectation, an expectation they're not even aware of, because you two never discussed it. Communication in marriage cannot be overrated, it is so crucial, and almost impossible for any relationship to thrive without it. So I'll recommend you work on your communications and get yourself a copy of my book, to help you with proven tips on how to achieve that blissful union you crave, in your marriage.
