If friends or couples don't trust each other anymore, I can't find any reason for them to be together anymore. To me, trust is something that is of utmost importance. It's the fundamental of friendships and relationships. I hate people who do not keep their promises and repeatedly commit the same fault. Stop saying "sorry" or "next time I won't do it again" when you repeatedly pissed people off with the same old reason. And hey people, if you can't tolerate,believe and trust that person anymore, please just leave that person. What's the point of hanging out with the person when you are doubting your relationship with the person? It doesn't mean that if you leave that person, you are a heartless, unfaithful, narrow-minded person. Some people really do not deserve your care and concern. Sometimes, you really need to ask yourself, do you really want to be together with someone whom you don't trust anymore? Even if it's just a small matter, but who knows what will happen next? I guess some people don't know how to let go of relationship/friendship. 勉强在一起是不会有幸福的。Imagine you are always angry with someone about the same thing, do you really think the happy moment in the past will offset it? My answer will be no. Sometimes, 放手是最好的选择，从此再也没有任何瓜葛。选择跟那些真的值得你信任和珍惜的人在一起吧。At least I think I made the right decision, so how about you? I rather be alone than having someone whom I don't even believe to be with me.
