How can you tell if your boyfriend/girlfriend is cheating? What are the signs? Can you tell ur story if any?

I am in a 3 year serious relationship w/ my bf he travels a lot for work, I been noticing a change in his behavior I want to know if ';cheating'; was the reason why he is different... Thanks for your feedbackHow can you tell if your boyfriend/girlfriend is cheating? What are the signs? Can you tell ur story if any?
Well if he's traveling alot doesn't necessarily mean he's cheating on u. The relationship is old enough for you both to develop trust and mutual confidence in each other. Just trust him. Best of luck. Jaja Precious-Nigeria.
