Normal to constantly think about my ex since i ghosted her?

I ghosted her earlier this year and I won't deny that I got with another woman.. That's why I ghosted her actually there was a French girl in my class at university and French accents make me drool so I got involved let's say okay and then we started hanging out at campus I ended it with my girlfriend of several years because I felt I needed something new and spicy.

I started Dating her. I loved showing her off to other people like look at this sexy French girl she's mine I'm in America so she's rare here like only a few in Maryland if any really.

Anyway okay months pass I keep hanging with her she's great looking and her accent oh wow then I keep going out and having a good time but why now I look at her like wait I don't want to be with you forever and thinking of parting ways and I keep now thinking of my ex who I did really truly love but then how could I do this to her if I loved her but I do love her she was my best friend and soul mate you know why did i leave her I get so down now wonder where she is.

I texted her no response now yes I ghosted her but that was months ago so she didn't text me but I finally text her and no text back. So now I think she doesn't care right what is my problem why did i do this help is it normal

My family loved my ex so much too this new girl they are so so about her
