The most common problem in a relationship is the so called third party. But there are times when the suspicion turns out false. When young girls would be asking me for advice on such problem, the first thing I tell them is to make an instrospection. Inspect yourself, your behavior towards your partner, has it changed? Sometimes we tend to change for the worse when we feel something is wrong but cannot pin him down because we have no concrete evidence. I’d say try to remain your usual self towards your partner but be observant. The best antidote to a third party is a much better relationship with more attention you give to him. Quarreling is not the answer.
