Does it get better with time ?

Ale
My boyfriend and I have been dating for almost 2 years now and things haven't always been great ... It's common for couples to get into arguments where one of us end up crying (me) but after a couple of hours we are back to normal ... But what happens when the arguement it's a constant thing ..? 
Have anyone ever been in that situation where you just argue too much with the one you love and feel like things might or might not change but at the end everything was still worth fighting for because you ended up happy ? 
I guess what I'm trying to know its if this whole argument cycle will pass and if anyone has been where I am and ended up living in a "fairytale"  and just end up with that significant other after all those arguments😖😢 and still love each other ... Please I need some feedback 😔
