Sometimes, it is not worth it to hold on to a sinking ship. I have seen a situation where a person you love is 'mistreating' you, but you are consoling yourself that it is going to be fine, she is going to change.
Perhaps they do change, but in most cases, you are the one hurting when you can win happiness elsewhere.
How do I know that I am stuck and I can't help myself?
1. You keep on thinking that your partner is going to change
In most cases, people who keep on telling themselves that their partner is going to change are the ones who are hurt more.
If you are giving love and you are not receiving it in return, it is time to break the loop, otherwise, you will be chained there forever.
2. You fear the unknown
You are not sure what will happen if you stepped out and moved on.
You are so scared of trying new adventures and you are actually feeling contented with what you are receiving.
3. You are scared to be alone
You are stuck with your abusive partner because you cannot let the idea of being lonely cross your mind.
You feel comfortable having someone than having no one
What you are not getting right is that it is better to be bored temporarily than not to be happy at all.
