stop being insecure and jealous when in a relationship

I got into somewhat of an argument…though it wasn’t as much of an arguement as it was me being jealous and upset that my boyfriend did all these things. It abruptly ended when he told me why he did what he did and I saw reason in his words and felt awful for what I said. I’m pretty sure that what I said was nearly unforgiveable, but he’s trying to prove me wrong on that one…

So the least I can do is be a better girlfriend for him. I don’t want to be jealous OR insecure…even though he loves me for who I am.
