Pay attention to the red flags. If something looks suspicious, then think well before you start building a new relationship with a person whom you cannot fully trust.
The guy is a hopeless liar
Creating a partnership with a person who lies to you is just a waste of time. Once a cheater – always a cheater. Do not even try to change him. And do not believe the guy if he says it will never repeat again. Respect yourself and do not let anyone make you feel an idiot.
