Relationships sometimes fail due to life's stress, lack of communication, and excessive baggage. I have had all types of relationships to fail, both(romantic and non-romantic) Xfriendships and Xboyfriends. The causes were always linked some way.( what causes???) All relationships need to have good foundations. It is up to all Xpeople (individuals) participating in the relationship to help support the foundation.
There are many Xthings (obstacles) that life throws at you that can cause stress. Sometimes no matter how you try, your daily stress can cause you to act differently towards the people around you. Often people take out their issues on the wrong people and it is (often) Xcommonly the people they have relationships with. You need to take the time to consider that the people around you might have had a stressful day as well. Take the time to discuss each other's day and comfort each other. Do not leave your friends and loved ones out of the loop. Discuss with them what is bothering you. By you pushing them away or taking your stress out on them, Xonly causes more problems.
Lack of communication or not knowing how to communicate is a common reason why relationships fail. People tend to have a strong desire to be independent which causes them to want to solve everything on their own. It comes so natural that they forget to inform the people in their life. There are people who Xjust choose not to share their issues. This can lead to lies and you can lose trust. The people you have relationships with will think you are hiding things. They will also feel like they are not worthy to hear your complaints and concerns. Your family and friends will stop sharing information with you and this will cause a distance in the relationship.
The baggage you carry with you can weigh you down. Baggage is usually regrets, bad experiences, emotions, and bad habits. This baggage is from previous relationships with family members, co-work...
