Jealousy , help ??

For starters, I get sooo jealous. I have been in a relationship with my man for 9 months, but I still find myself getting jealous over the smallest things. When he looks at another girl, bumps into them, etc. Now, recently I found out that every time he told me he doesn’t find any other girl attractive, he was lying. I guess I kinda pushed him into saying it, but he still lied. It was probably a bad idea but I kept asking what girls he thinks “looks good” and on that list was the girls I was so worried about last semester. I don’t know what to do, I’ve been a wreck for the past day and a half. It’s taken over my life. Many many many times through this, he had told me even though they don’t look terrible, it doesn’t mean they’re “pretty” or “cute” or “beautiful” , he told me I’m the only one who are those things and that I’m the most beautiful girl in the world, several times. I just still get jealous, especially since I’m my opinion these girls are gorgeous, and I can’t see myself as that. I think a reason for that was the past “relationships” I was in, I was stripped of my confidence. So, what should I do? I get hurt when he finds other girls attractive but I know he wouldn’t ever act on it, I read a bunch of things on the internet and a bunch of them said that guys look and fantasize about other girls they see, but my boyfriend strictly said he definitely does not because I’m the only one he wants and needs. How do I get rid of jealousy though ?? It’s such a bitch on my emotions
