If you think your relationship is at an impasse and has no future, it may be worth considering ending it. The sooner you break up, the easier it will be for you to get over the breakup.
The reason for the breakup
Think about why you want to dump the guy? Perhaps you think the guy treats you badly, you have lost interest in him, or he is not ready for a serious relationship. Once you figure out the reason why you want to dump a guy, you will know what and how to tell him. If it turns out that you no longer have any feelings for him, you will need to find a way to tell him about it. Honesty in a relationship is important, but if you don't want to hurt your boyfriend, you'll have to prepare him to break up.
A meeting
Don't try to break up with your boyfriend without dating him, such as texting him or even calling him. If you have a long and close enough relationship, you need to talk to him face to face. Otherwise, your boyfriend will still reach out to you, he will look for meetings with you. Again, you will have to return to painful conversations about parting, but in new circumstances.
Once you've made the decision to dump your boyfriend, it's important to do so as soon as possible. Choose a moment when you will be alone, at the same time, you should not be in a romantic setting. Do not talk to him about parting in places where you are often together, do not do it in public places. Choose a time when he will not think about his problems.
Speak straight
Tell your boyfriend the truth, tell him straight out that it's over. Avoid words like "let's be friends" or "it's all about me." They will only sow doubts in your sincerity, the guy will think that you have not fully figured out your feelings, he will have hope. Talk to him looking into his eyes, let him see that this conversation is also not easy for you. Let him know that the relationship is at an impasse and it's time for both of you to move on, each in your own way.
It is possible that the guy will demand an explanation, he will ask you about the reasons for the breakup. Speak as is, but try not to hurt his feelings. If you have specific examples of why you are dropping it, please provide them. Perhaps the reason for your breakup is that you are incredibly angry or resentful towards your boyfriend. Try not to express feelings, be rude and shout. If he really hurt you, you don't need to be very polite to him, but don't turn the conversation into a showdown.
Be short, if you decide to dump the guy, try not to drag out the conversation. A long conversation with tears will hurt both of you. The longer you talk, the harder the breakup will be for both of you.
