It's very difficult to see what's best for yourself when you're invested in a relationship. Sometimes, you benefit from it and sometimes, you lose. You can start to lose yourself and forget to make yourself and your happiness a priority if you are in a toxic relationship. If you feel like everything is not  right between you two and you are in an unhealthy toxic relationship, then maybe that 'feeling' is actually that little voice in your head telling you to get out of that shitty relationship and save yourself.

When you are not comfortable with your significant other and have to hide things from them, then you've lost that bond on which your relationship was initially built and things are not really good for you. Jealousy and the blame game also ruins a relationship and makes it toxic for both the partners. Little bit of criticism is fine in a relationship where one tells the other about their flaws or negative qualities so that they can improve themselves. But when criticism is used as a channel to express contempt or disdain for someone else, it can make the other person feel unvalued and worthless. When you reach a point where you're either fighting all the time or there is absolutely no communication between the two of you, it's time when you have to reevaluate your feelings about each other and thoughts about the relationship.

If you cannot tolerate your partner's presence around you or try avoiding each other, then you should really just quit. If your relationship changes you, it should only make you a better version of yourself. If you feel like you're losing yourself or you don't recognize who you are anymore, it's not healthy for you. Also, if you're constantly trying to make them happy but you're not getting anything in return, then something in the cycle is disjointed because happiness should be mutual and not one way. Any relationship wherein you feel emotionally worn down and threatened should be walked away from. If you are constantly put down and you have to give up on your wishes and your beliefs only to please your partner, then you are definitely headed on the wrong path.
