I'm 17 years old and have been spilt from my boyfriend who is 18 years old.
Me and my ex boyfriend never had a great relationship, it seemed like he was never really interested in me, although sometimes he made me feel so special.. He was a cheat and a liar, but instead of ending things, I would simply get revenge. I didn't want to lose him and in a strange way I enjoyed the games in the relationship. We would always spilt up and get back together.. But he was more focused on his friends rather than me.. As a year and a half went on I was getting more and more hurt. Then finally, I ended things in the heat of the moment and immediately regretted it afterwards, but because it was the first time I ended it, he wouldn't take me back. My best friend was getting me through it and was always there for me, we had been friends for many years and she was the person I trusted most in the world, we were stuck together like glue.
Until one day I went on her phone too see that she was texting my ex boyfriend. Because I wasn't over him and I was still in contact with him, I was absloutely furious with her but forgave as she promised never to speak to him again. Afterwards, my ex boyfriend came back from working away and we saw each other again, he was very distant with me and things didn't feel the same, although I did still love him with all my heart! He then started ignoring me and telling me to move on and that he was over me.. I was completely heart broken, but so desperate to get him back. A few weeks went by and my best friend also became very distant with me.. I received a text one day from her telling me that she was with my Ex-boyfriend and that she was sleeping with him behind my back. She apoligised but explained that she wanted him over me. I was completely distraught. The two people I loved most in the world had completely betrayed me and I really don't know how I can ever move on and forget it. I still try and contact my ex boyfriend, even though he tells me he's happy with my "ex" best friend. And my "ex" best friend I don't want to see ever again.

It's a bad idea to ever contact your ex, especially when he has said that he is over you. Staying friends with him now is like, your mother tells you that your dog is dead, but you can still keep it.

You should immediately go "no contact" mode. As soon as possible. And as for your former best friend, I'm sorry about that, it happens a lot these days. It will probably close you down and make it harder for you to fully trust anybody in the future. You know what they say; screw up, and see who's left. Those who are left, are your real friends.

I'm sorry you had to go through that. I went through something similar. I lost three best friends in the same week, one was about an ex but under different circumstances. It absolutely hurts to be betrayed by a boyfriend, but it hurts much, much more to be betrayed by a best friend. In this case, you've got a double dose.

The way I was able to get past it was to realize that if my "best friend" hadn't betrayed me now, she was the kind of person to betray me down the road, and she had probably already betrayed me before. People change, some for worse, and some for better. And sometimes people changing for the worse allow people to change for the better. You've learned a valuable lesson from this, you've grown up a little bit more because of this. Take what you've learned and apply it to future endeavors.

How can you over come boyfriend and best friend betrayal?
Cut them from your life, and get better friends.
