Sometimes it's very obvious that your partner is taking you for granted and other times it's so subtle that you don't even notice. If you suspect that your partner isn't treating you right, you're probably correct. Here are some ways to notice when you're not being appreciated:
THEY DON'T TREAT YOU WITH RESPECT
There are different levels of respect in relationships, some basic and some are more nuanced. It's important that they at the VERY LEAST give you basic respect like thanking you for cooking a meal or cleaning up. Simple things like that go a long way and make a huge difference in how your feel about yourself and your relationship.
THEY DON'T INVOLVE YOU IN THEIR LIFE AND AREN'T INTERESTED IN YOURS
This might seem silly - of course you're involved in your partners life.
...but are you, really?
Do they get your opinion before making decisions? Part of being in a relationship is having your presence valued in their life and if they aren't coming to you before making big life choices then you're missing out on a huge chunk of their life. So maybe you're not super involved in their life - are they involved in yours?
Does your partner ask how your day went, what's new with your friends, how you're doing with your hobbies? If the answer is no, you may need ask yourself why you're with someone who shows so little interest in you.
THEY AREN'T FAITHFUL TO YOU
If your partner cheats or has cheated on you then that's a pretty obvious sign you're not being appreciated. An immediate solution to this problem is to end things but we've all seen relationships that are able to overcome this type of transgression.
People cheat for all sorts of reasons and not one of them is valid. If you're married, have children, or own property together then it might be worth trying to work through this but if you're choosing to stay out of fear of being alone, you really have a lot of internal soul searching to work on.
THEY MANIPULATE YOU EMOTIONALLY
If you find that you're being manipulated emotionally it's immediately time to get out of this relationship.
You may find that you're having to constantly apologize for things you've done or said of if you are the one who always has to compromise then it seems like you're in a controlling relationship.
They possibly engage in a makeup/breakup cycle where they randomly decide they don't want to be with you, forcing a breakup (on their terms) and then again leaving just enough breadcrumbs for you to wait around for them to decide that they're ready to get back together.
There are so many more but if your relationship checks off any of these boxes, it may be time to do some real thinking.
