How to stop overthinking things in a relationship?

It's important to remember that in a relationship, everyone has the tendency to overturn things. Your partner is likely having similar thoughts. Everytime you get into the pattern of overthinking things, take a step back. Breathe. Maybe write down what you're feeling and realize that it's one thing, not a thousand things.

Sometimes in a relationship you need to stop and think through your emotions and put thought into whats real and makes sense versus what is you overthinking.

Think about yourself more than what your partner thinks of you! Sometimes we humans can't help it, but it's important to remember to love yourself just as much as, if not more than, the other person loves you.

Try not to focus on the eventual outcome of the relationship and the end game - whether it be sex, marriage, or whatever else. Just focus on your current situation and whatever makes you happy now.

Give your partner the benefit of the doubt, until nothing is concrete then just keep minding your own business and focus on your relationship and how to deepen it, trust them that they are doing right by you and you the same way to. In the end they can either grow and acknowledge all the trust you've given them or they break away because of the lies they told and no longer want to honor you.

Take time to appreciate the things you have. Don't worry about what might happen in the future. The more you think about what might happen, the more you ignore the wonderful now that is right in front of you.

Trust your gut instinct if the overthinking is a result of jealousy, trust, or fear, if you think something is wrong then the relationship isn't working for you and you will only be more upset the longer you drag out this feeling. If you are worried about things like "what are they thinking" "why do they do this" etc, then communication is the key...just ask them. Having open communication in a relationship is important, as cliche as that sounds, just talk to them. This builds trust and honesty, and most of all it can answer your questions. If the overthinking is about something they did that bothers you, again...communication is the key "I don't like it when you ...." or "It bothered me that you...", you could start it with "I need to talk about something and I don't want it to upset you but it's on my mind" type statement. If you are intimidated by talking to them directly, try talking to a friend or writing it all out in a journal and think of all the information you have and the perspective of the other person. You can make your decision about the situation after you've fully thought it out.

Firstly, in a relationship you must work on yourself and make sure your partner is doing so as well. Relationships are about two individuals coming together and making a "whole." Communication is key when overthinking happens, along with self-soothing. Dialectical Behavioral Therapy is a great thing you can do on your own when you are feeling overwhelmed with thoughts. Meditation (via youtube guided meditations) , even for five minutes, can distract you so that you can have increased clarity on a situation. Everyone overthinks, and you are not alone. Relationships are very important to us, and it is pertinent to remove yourself from the overwhelming thoughts so that you can come back to it with more of a rational mindset.

Live for the moment, respect yourself, accept that you are in the relationship to fulfill your needs and not only the partner's needs, you are here to complete a half, not to live the other's life.

Trust and honesty. Reassurance and give security. Communicate often and proper way. Think positives, not the negative.
