Past loves

Does anyone else have past relationships that they know they won’t forget or like stop missing because they were a big part of your life?

My current boyfriend of 6 months gets mad at me because I will never forget/stop missing my past relationships even tho I’m over them and I’ve moved on. Also he gets mad when I don’t text back within a minute or so and he asks who I’m texting as if I’m cheating on him, I’ll admit I did do it in past relationships but I never do it anymore, he doesn’t let me text guys(most of my friends are guys), and he made me delete all guys from my contacts so now the only people I text are him and my family and I have no friends. Any advice on what I should do, it’s starting to really get on my nerves that he doesn’t trust me
