Fights , arguments , and , having different view points can be a part of relationship and there is nothing bad about it. We all are humans and we all are having different heart and brains.
What might be liked by might not be liked by others. There will come many different occasion when you will have a fight , it can be any reason maybe a silly reason as well but you will face this situation someday in your life.
There will be lots of arguments because a relationship without arguments is like a sea without water. So you have to be ready for that as well because when you will be ready for that you will handle arguments easily.
Lastly when it will come on what you think, what is your point of view about a topic again there will be emergence of anger and sadness because of different view points.
You see the three points i mentioned above , despite all these things sounding bad to ears the reality is that everything of this is normal in a relationship and one should always be ready for the ups and down.
The main thing that i want to say is no matter what comes into your relationship from the above things or anything that you can think of , if your relation is not harmed from it then you should be alright.
If you are lucky enough and can manage things then your relationship will only become strong with every fight and arguments because with every fight and arguments you will get to know each other better and by that you will be able to build a healthy relationship.
So take things in positive way and then you will the real change in your life , a positive change.
Thank you
