You can always tell when your significant other is cheating on you. One blatant red flag is when he starts lying to you and saying he's one place when you know he's somewhere else that's a huge red flag.
He's not to be trusted and isn't worth the hassle. Get out and get out now!
This started happening in the middle of my relationship with my guy.
I found him at a place which was not where he said he was and with another woman at that! I broke up with him immediately!
