How do you know when it's time to break up with someone?

I think there are certain signs that sort of hints that a break up is very much needed. The pros and cons in a relationship can better help you make that decision. Ultimately its when you feel that this relationship is toxic rather than good.

It is time to break up with someone if they hurt you, annoy you to the point the might make you dread seeing them, when you don't like them anymore, when they make you uncomfortable, and you don't feel safe, and when you feel it is the right time to break up.

When you feel you would be better off without them, and can imagine a future without them in it with you.

When they physically and/or mentally abuse you. Trust your instincts and do not be afraid to be independent

When your not happy. When you feel the relationship has gone left. When nothing is the same anymore if he hits you. Or if he or she cheats.

When you are not happy with that person anymore or vise versa. When you can't make each other happy.

Parting ways with your partner is almost always difficult especially when both of you have shared so many memories together [both good and bad] and it is not in you to be the first one to walk away from relationships because you care enough not to hurt someone else. Before anything else, be sure that it is what really wanted to do. When there are hesitations, consider thinking about it some more before deciding to part ways with your partner but you will know when it is time for you and your partner to go on separate ways when: [1] You and your partner no longer connect with each other in a deeper and more intimate level (this meant that both of you are no longer on the same page with regard to your values, beliefs and priorities in life). [2] You and your partner no longer try to work together as a team to make the relationship last (this means that one (or both) of you no longer care enough to resolve any conflicts that emerges in your relationship). There are other ways to tell but this is usually the most common reasons. Please remember that it is never good to go on separate ways when It is due to your emotions (meaning you just feel that you don't love that person anymore). Emotions are always on the spur of the moment. Perhaps you feel that there's something missing in the relationship and because of that you'll want to end it without even trying to resolve it together with your partner first to see what else could be done to make your relationship work. It is good to remember this: "Never let the sun go down on your anger [Ephesians 4:26]" or to put it simply, never let any conflicts go unresolved at the end of the day. Try to resolve it together first before anything else.

When he start to ignoring you and never consider your feeling anymore. When both of you always fight over a small matter . When you don't feel anything toward him

Honestly, you never know, it's like your mind comes up with these excuses that account for them hurting you or the relationship being the way it is. So I knew I had to break up my ex when I started questioning my feelings and thoughts. Also, that's when I began looking for something beyond the relationship. It's such a dilemma but if you are young(I am not it is okay to break hearts) but it is okay to break up if the relationship no longer makes you happy or helps you grow as a person. I would say cultivate friendships instead because that is the foundation for any good relationship.

When you are in love with your memories more than the person who stand in front of you. That's when you know you have to walk away.
