"friend" some friend she was....😠

Okay so I have been with my boyfriend for almost 10 months now and I am really, REALLY happy with him. He is my world and I never want to lose him. Yesterday he told me something about my previous friend that I didn't know. He never told me this before we left school cos he knew I would lash out at her and didn't want me to get into trouble but......she messaged him a few time in the middle of our relationship and tried to get him to cheat on me with Her! Now to give you a little background here my boyfriend is her ex, but I went out with him a whole year after they broke up and she helped me get with him. So it's not like she was particularly against it. I even asked if it was okay since I have liked him for like 3 years. But yeah she had been messaging him half way through our relationship saying she wanted to shag him and that she could give him what I can't (we haven't had sex yet because I have anxiety about the pain and possible pregnancy that I need to get over first and he understands that and is very supportive) And trying to get him to meet up with her. So he said he would once to put her down gently. So he met up with her and explained that it couldn't happen since he doesn't like her in that way and he has me now. Well she didn't like that and tried kissing him to which he stopped it and told her once and for all that he does not like her and she stormed off. All this happened at the same time that she messaged me calling me all sorts of mean stuff, saying I'm a cow and that I am using my boyfriend to which I most certainly am not. I love my boyfriend. But she has always acted weird with me since I started going out with him. Now I know why. This was a friend that I have had for 5 years that has betrayed me an I don't know how to react other that really really angry. These are the messages she sent me

I am none of those things btw. All my friends disagreed with her and she even apologised later on which I still don't accept but I was civil with her, I really regret that now.
