Is it normal that my ex is taking his new girfriend to the same experiences and places I introduced him to when we where together ... ?

The reason why he takes her can vary:

It means he enjoyed those experiences and he wants to ensure she enjoys her time with him, so it's a safe bet!

He's lazy and too uncreative to come up with new memories to make with her!

I promise you once she realizes he's taking her to all the places you took him, he's going to look straight up like a LOSER lol. However, I'm sorry in advance for being so candid but I advise you take this as a sign and stop paying attention to his life! HE'S NOT WORTH IT! If a guy is taking her to places you once went with him it mean's his associative memory isn't kicking in which typically means emotionally he's moved on!

I'm sorry! WHAT a jerk!

P.S "Normal" is relevant to the person.

I wouldn't do that.. but I think you should move on in life.. I know it hurts and it's easy for me to say..

sure

yes normal

It serves two purposes! First, it makes YOU jealous. Second, you showed him what a woman wanted, so he's able to impress new GF!
