Loveable Mermaidz

I have a question, if your in love what would you do to keep them from leaving? I mean love is difficult right and it depends on the way the guy or girl that you love acts. I mean if they acts childish but u love them anyway what do you do when they hurt you not physicaly but emotionaly? What if they act to mature and dont know how to have fun how do you let them know they need to ease up a bit? Or what if they are both but dont know when they need to be serious and when they need to have fun how do you tell them that they are emotionaly hurting you without having to get into an argument? What if all you ever do is argue? What if you never figure out how to make a compromise no matter how hard you try? What if after all your trying and fighting and making up and having fun and being anoyyed you get tired of it all and just want to move on but you love them to much to do that? My bf hurts me emotionaly and he doesnt even realize it. Im his first gf nd he dont kno exactly what to say when certain things happen but idk how to deal with it. We argue alot and whenever we hav a fight and stop talking whenever i walk away i start to cry and i dont lik crying. What do you do when you have no clue what to do and everyone and everything is against you? What would you do? What would you say? How would you feel? How would you deal? What if it  all just ended then what?
