Every relationship is anchored on trust, love, personalization and fairness.
But the moment you begin to suspect your spouse, husband or friend, love - which guides the trend of the relationship - disappears and trouble takes place.
A wife/husband or lovers who give room to third party is prone to welcome negative ideas which will definitely lead to suspicion and the resultant force may be separation/guilt by either of the parties.
One thing you should note is that the time when the relationship was instituted none of these people whom you're reporting the issue were not there and may not have been in a relationship before, or have no good intention for your relationship.
By this notice, you're not suppose to discuss your relationship with anybody for it is not healthy, rather any issue that arises should be discussed by the both of you without welcoming third party no matter how serious the case may be to avert suspicion which may proximate distrust, reduction in the level of love you have for your fellow in the relationship.
However, once you begin to notice abnormality in your relationship, don't be upset, call the person in question and trash it out with him/her and erase it from your mind there and then, but failure to do this you'll have your mind poised and nothing he/she does will interest you any longer.
In conclusion, suspicion can destroy the future of your unborn children, business, office, association and your plans chase unit away from your household and heart.
Therefore to recede from this kind of negativity, always be satisfied and appreciate your relationship and everything that comes out from it.
Also, learn to have open dialogue instead of concluding issues without hearing from your friend.
