If I'm in the middle of an argument with my sister, would it be bad of me to not attend her wedding?

Perhaps seeking advice from a loved one is the best answer I can give.

Life is too short to carry grievances.Being bitter over someone will have a negative effect on yours and nthe other persons well being.You will have regrets down the track and sometimes  a situation comes up where a loved one becomes seriously ill and it becomes too late to say your sorry for your actions.You don't want to carry that guilt for the rest of your life.Put yourself in your sisters shoes, would you want that to happen to you.

Try to reconcile before her wedding, if not just bite your tounge and turn up for her special day. Most arguments although seem horrific at the time but later on down the track it will be trivial. Try putting yourself in her shoes and how would you feel if she did not attend your wedding.

Hope you both have a wonderful day and the love stays with you forever.

Not attending the wedding will only compound the argument! Even if you're still not talking, I think best to be the bigger person and attend the wedding, it would mean the world to her to be abe to see you there. 

Family, I think, are like partnerships, in business, you may not always agree with your partner, but you decide in favour of the partnership. Family stick with eachother and support eachother through the most difficult times, that's what family is for, we forgive, we apologise, for the benefit of the partnership. 

Perhaps, imagine if the situation was reversed. What if your blood sibling, was not present on your wedding day ........  we don't know the issues involved in the argument, but is it worth it?

I sincerely hope you work it out with your sister and on the day, you embrace and take a fabulous (smiling from ear to ear) photo to remember the occasion.

yes you will regret for the rest of your life

Marriage is forever and a wedding is a symbol of the first step in that journey, The photos are taken for memory but also the ceremony itself, the vows you say, the family members and the guests just being there are all part of that memory.

What would you like to look back on as a memory of your sisters wedding ?

Arguments don,t last long but the impact of not attending your sisters wedding will last for yearsyou be the judge

Hopefully you can resolve your differences before her special day but if not, rise above the argument and don't let it spoil her happiness.

Familly support means everything to people on their wedding day - I've heard that hundreds of times. It probably means a lot to your sister too.

Arguments can be settled if you take the time to look at things from both sides whereas the hurt that could be caused by not attending her wedding may never heal.

I'd put aside whatever the issue is and make sure that your sisters wedding day is a special one for her to remember.  You won't regret going.
