How can I stop being jealous?

My friend just told me that she just met a new friend in Minecraft and that he is nice. But I'm kind of easily jealous and I don't know how to stop it.

Well I understand that you worry a little and being jealous is normal too. But it can't be too much, and when you get to know Minecraft, you shouldn't worry at first.

Being a little jealous is just part of a relationship when you love each other.

As long as it doesn't get sick, everything is fine. I've had experiences with it myself, my ex boyfriend has already ticked off when I was seen on my profile picture and said I would consciously take such pictures so that guys write to me, which is total nonsense
