It hard to accept when something good turn to bad, moreover to keep holding on or giving in.
Relationship is sacred, but the best thing to offer is friendship. I can’t demand so much but yes, I have "deeper cravings for some kind of sincere companion" because I can forgive a mistake but I cannot like, love and live with an untrustworthy person. Yes, in life there is no such thing as ‘we can live happily ever after’. There will always be some unexpected problems; and we only need is to learn to solve in amicable way but when I have nothing in common with another person, I feel like a stranger, to be in conflict with people is tiring.
These days it must be hard to trust somebody outside family. But I think there are still good people everywhere in the world..
