When the bad outweighs the good... I say go through a few days of missing him, you'll see how quickly you get over him and how much better you'll feel without him. Relationships are suppose to be means to a marriage... So if this is already a huge issue then it sounds like a waste of your time. It is hard to let people go especially in the new phase when things are exciting.. But it sounds like ya'll skipped the new phase because ya'll already arguing and knock heads. good luck
