Many of people think that to end a relationship is a troublesome and ugly routine.
"Many of people"很怪；that變成從句很累贅.還有end a relationship怎么會是routine?（除非經(jīng)常甩人）
建議：Many people think ending a relation is a troublesome and ugly routine.
Here are my personal suggestions that might be able to help you enjoy such a process without worries afterwards,which means ending thoroughly.
"which means“沒有錯,但是這句話等于重復內(nèi)容,建議去掉.
Firstly,show your great unwillingness as well as sadness to your pre-ex about breaking up.
正宗的英語其實沒有firstly這個詞,只有first：）.
This is the very step that lays foundation for all the followings,because you need to convince him or her that you really do not want to do this,from the bottom of your heart (of course it is fake).
This is the very WHAT step?
For example,say “l(fā)et’s end the relationship” but add “I love you” at the moment the weeping wretch is turning around and going to leave.
不知道你這個文章多正式.weep wrench似乎用的不妥.（還有你這樣可是給人家錯覺還覺得有機會啊,怎么thoroughly甩人啊?!）
It is certain that he or she will come back to you; nevertheless,please do not respond to that person.
語法無誤,但是內(nèi)容自相矛盾了.不太明白你這個response該怎么理解（說愛ta然后突然不理ta?）如果一定要加這句,貌似應該放在總結(jié)那塊.
不要用certain,because there are always exceptions.Certain,never,always這種詞要慎用.
建議：It is likely that the person will come back to you;...
And here comes the good show.
很口語而且看上去超級arrogant,不要在文章中用.建議去掉.
After you speaking out such a fantastic dialogue,your ex must come to find you.
speak out dialoge?!!!第一：DIalogue 指對話,兩個人才能進行的.第二：什么叫must come to find you?意思是你ex會對你有留戀?
建議：After the conversation,your ex will likely think there is still chance and try to mend the relaitonship.（這里我編了,因為不明白你想表述什么）
Now,you need to show some acting skills（你早就在acting了）—sometimes being considerate and sometimes merely feeling guilty.
你是說這個acting being considerate還是你自己being considerate?修飾的主語不明.
這句話很拗口.而且前面已經(jīng)acting那么久,又矛盾了.
建議：－ 后的內(nèi)容不要,
There is no doubt that your ex will ask what are you really thinking again.
there is no doubt 和 certain一個問題.ta前面有沒有問你what are you thinking?何來again?!
建議：Chances are your ex will ask you to think twice about breaking up.
It is likely that your ex will try leaving you,and thus the third step is to make him or her stay.
我以為你第二步就make人家stay了?!
will try TO leave而不是try leaving.
In spite of indifference in ordinary days,you are supposed to show how you care about him
or her in special days,such as the birthday of your ex.
不要用in spite of,你后面那么多in in in,讀上去很怪.用despite
you are SUPPOSED?有什么規(guī)矩要怎么show么?還有你后面解釋的也不清楚,怎么個special way?
建議：special days.For instance,(后面去掉直接開始舉例）
Tell him or her that you have spent over totally a month to make a birthday gift,but in the end,
you have not given him or her because you do not want him or her misunderstand
your attitude,which is “we have broken up”.
in the end,去掉.（而且你后面又用end,不要重復）
The end comes as your ex is heart-broken,and actively say farewell to you.
!無法理解ACTIVELY say farewell to you.前面一句完全是病入膏肓句.
Moreover,your ex probably will not find you any more for his or her fear of you.
find you any more什么?
建議：your ex probably will not find you insteresting as he/she got wholely tortured with this breakup game with you.
So do not worry about that your ex will interfere with yourlife.
do not worry有點斷章取義的口吻.
建議：so you won't have to worry about your ex bug you in your life no more.
你是個妹子吧?寫這種奇葩文.
如果完全不討論context & content,這篇文章的語法還算ok的,但是上下文很散亂.
如果討論context & content,我覺得會搞這個東西的人相當dipoler.
不謝.This is the very stepVERY 不是有exactly的意思嗎？我是參考Sheldon"Hey.Leonard, is itawkward for you knowing that one of your dear friends had sexual intercoursewith a woman you used to love in the very place you lay your head?"From Big Bang Theory??你這種美劇的東西，建議正經(jīng)的文章不要隨便用。用法無錯，但寫作文和平時說話總是不一樣的。
