Your partner is meant to be the one person you can talk to about anything. But if they avoid talking about things important in your relationship, it could be a big problem.
Being able to talk to your partner without fear, without judgment, and without having to worry about it turning into a brutal argument is important to have a healthy, loving relationship with your partner.
Even when conversations may be uncomfortable, they are necessary for your relationship. And when you see that you can't openly talk to your partner about the important things, it can be damaging to you and your relationship. If you can't ask your partner these questions, you might not have a healthy connection with your partner.
When your partner is never ready to talk about the future and always avoids the subject when you bring it up, it could be that they don't see a future with you. Whether it's marriage or having kids, your partner should at least be comfortable sharing their opinion so that you are both on the same page. When they can't give you a commitment but they still drag you along, it could leave you feeling unsatisfied in the long run when you don't see any progress.
While even the most healthy relationships have arguments, you would want to have these exchanges in a way where you both are able to meet each other halfway instead of just you carrying the entire burden. But when you suggest a compromise and you see that your partner turns it into a competition where only they want to win, it shows that they only care about their own needs and will always neglect yours.
Your partner is meant to be the one person who patiently listens to you without judgment, while they do the same for you. But if your partner always shuts down and is never comfortable about being vulnerable with you, it can get in the way of your relationship with each other. You and your partner should be able to share your innermost thoughts with each other without hesitation, making your relationship feel like a safe space for both of you.
By asking this question, you are essentially getting to know your partner and their needs better. But if they avoid this question or they don't care about what your answer to this question might be, it could show that they are not bothered about taking your relationship to the next level where you both feel more connected and intimate with each other. Also, if they answer this question but are not ready to hear what you have to say, then it could be that they are not flexible and are not ready to see your perspective.
When you share a relationship with each other and especially share a roof together, it's important that you both are comfortable discussing finances with each other. When they are not ready to talk about money matters, even after spending several months with you, it could also be a warning sign that they are not sure of having a future with you. Moreover, money shouldn't be the kind of thing that comes in the way of your relationship where your partner feels like they have to hide things.
The physical intimacy you have with each other is a reflection of just how comfortable you are with each other. But if your partner doesn't want to talk about it or they selfishly want only their sexual needs to be fulfilled while ignoring yours, it could show that they are in general being dismissive of your feelings. In a healthy relationship, you would be able to say what's on your mind, even your sexual desires, without having to worry about anything.
Changing and evolving is part of a healthy, long-term relationship. But if you see that your partner constantly brings up the past just to manipulate you into doing things you don't want to, it could hurt your wellbeing. Ideally, you and your partner should be able to trust each other fully, talk about mistakes, and then be ready to take the next step hand-in-hand, rather than be rigid and fixate on things from the past that cannot be changed.
