Should I be insecure over a guys ex?

i met this guy he’s a pretty cute guy he’s 22 and I’m 21. I know he has an ex who’s a year younger than me and she’s pretty she has a prettt face and is skinny but is also curvy so basically the perfect body. I know they were together for a long time I’m not sure why they broke up but I get told that I am pretty. I know that I have a cute face because people have told me before but I’m a little bit of a chubbier girl. I’m not super chubby but I am chubby and that kinda makes me insecure cause he has a pretty ex and obviously they’ve done stuff together. And well im nothing like her physically so im just curious should I be insecure over his ex? Do guys even compare new girls they talk to to their ex? Should I let it go? Lol I don't know maybe im thinking too much. It might have to do with the fact that I was wayyyy chubbier when I was younger and I lost a lot of that weight but I’m still chubby so I’m unsure of myself because now I’m getting complimented all the time when I used to not get complimented at all.
