I need help with my jealousy.

I get really jealous and bothered when my boyfriend tells me about the girl friends he hangs out with or talks to (and please I already know it’s wrong so don’t bash me for that). Just recently he said he was talking to his drunk girl friend who broke up with her boyfriend and I got all jealous. I don’t want to feel like this. I’m just scared that someone is going to take him away from me or he’ll realize he’s in love with one of them. I just hate seeing him give other girls attention. Again, I know it’s wrong to think this way and this kind of jealousy is toxic and I’m just asking for help kn how to better myself because I don’t want it to ruin the relationship. I haven’t done anything dumb yet. I told him I felt jealous about him and his drunk friend but he didn’t really say anything so I just dropped it
