That’s not the kinda thing you should worry about when you are getting into a relationship,the same way you shouldn’t think about “what if we get a divorce” when you’re getting married.the thing is darling when you’re in a relationship you have to accept the fact that your significant other will hurt you in some way but what you have to ask yourself is is he/she worth it?,does there good personality outweigh there bad?.so what I’m trying to say is you just have to find the person who is worth the pain.
