Anger is beneficial to relationships
As the saying goes - the heart grows fonder with time and distance (or something like that), there is also a saying that goes something like this - arguments and fights grow people closer together. This saying (unlike the other one in my opinion), is very true in the sense that when you argue with your significant other, you are teaching and learning each others’ boundaries. When you keep your frustrations and anger inside, all you are doing is letting your partner know that what they are doing is okay and so they continue to do whatever it is that makes you angry. This can be very detrimental to any relationship. So, if you use your anger to solve problems other than vent and rage, then a strong and close relationship is what you will have
