Reasons why Relationship doesn't last long

These days, some relationships don't last long. It falls on both opposite sex in a relationship. We have many reasons we ourselves could figure out as the main problem. But I'll only discuss the most common reasons why relationships don't last long.
(1) Cheating : We are in computer age where technology develops everyday. With this it's very easy for whosoever in a relationship to cheat. Mind you cheating in a relationship would have a certain reason which at the end of everything the love for each other will reduce drastically. Meeting new friends having relationship with them via social medias has great impact in a relationship.

(2) Trust : When trust is lost, ability to stay longer with your opposite sex will reduce drastically. Why? Many people are in relationship for many years without trust, mostly leading to cheating because they don't trust each other. By so doing the height of their relationship will reduce.

(3) Care : If you love each other, you will surely care for each other. But when there isn't any care. You don't want to know if it hurts or not, many things. Believe, you are lucky to be with him or her but when another outsider shows too much care to your opposite sex, how would you even cope. Mind you this especially goes to the ladies when they realize their boyfriend doesn't care about them. But once they could recognize another guy showing them love, caring for them, they would love to go along with that guy. By so doing you would say your girlfriend breakup with you. It isn't funny but the truth is it is normal for a guy to take good care of his girlfriend so that she would not look up to another guy if there is real love between you two.

(4) Too busy: These days, for one reason or the other you don't take time to have fun with your opposite sex not to talk of having time for your relationship. If this is happening, being too busy for your relationship. Staying forever together is 20% assurance. So tell me how will your relationship last long, impossible!

(5) Sex : These goes to both the opposite sex. You would like to have sex with handsome guys or beautiful ladies meanwhile you are in a relationship with another guy or lady. If he or she later founds out, he/she won't trust you and by so doing; getting bored or fed up in the relationship will start getting stronger.

(6) No one is ready to be a fool for love : Relationships don’t last these days because this generation doesn’t understand what it means to love someone madly. We are just too realistic for our own good and we don’t love madly anymore. No one is ready to be vulnerable by letting go of themselves. We have become too smart for ourselves and this is affecting our relationships today. We no longer want to be a fool for love.

(7) Lack of Communication : Communication can make or break any relationship. Having lack of communication can range from the tone of someones voice, and how they respond to things to someone who is just horrible at listening. This can cause a ton of problems and can turn easy, solvable misunderstandings into mountains of mess and if not continually worked on gets harder and harder to repair. It can also lead to other things like one-sided expectations as stated before, Misinterpreting your goals, and wants to be the same as your partners, and insecurities with your partner as to your true intentions while in the relationship. Be mindful that communication with your partner isn't something you master over night it can take months or years to gain a solid ground of communication with your partner. Simple things like acknowledging your bad communication habits can put you on the the right path to better communication.

In all of our relationships, despite all the problems I pointed out in our partners, the only common denominator is us. We are the only person we continuously bring along into each new relationship. So what did you think about this?
