Jealousy

I had never been jealous in our relationship until a couple months ago. I had noticed how many girls pictures he had been liking some of half naked girls and every time I saw all the likes it made me more and more insecure. Also caught him deep in a girls profile on a pic of her half naked that he constantly used to post about saying he wish he could fuck her (before we were together) like yes she’s “insta famous?” but I don’t know it set me off. Now we constantly argue about some girls which is my fault because of how jealous I’ve gotten. I hate it so much I want it to stop but every time something happens I can’t control it and go off. What can I do I want this relationship but I want to feel that I’m good enough.
