You are absolutely right! Sometimes some women always jump in to conclusions at once without having the legit evidence or knowing first the real story. Assessing yourself first if you are not paying too much attention into the relationship might be the reason why you are suspecting that your partner had a third party. That is why do not react too much if you are having this kind of suspicion. It will not not do good but instead find ways how you can put more love and romance into the relationship instead of thinking and acting negative.
