Need some help...

Blue

I'm having a hard time with my insecurities. I'm currently in a great relationship with a truly wonderful guy but I'm pushing him away. I'll get jealous of really insecure about small things. I keep letting my mind get control over me. I'm scared that my insecurities will cause him to leave. He's hasn't done anything wrong at all. I e just been hurt by every single guy I've ever been with so now having an amazing guy it's really been hard for me. I'm cause him not to be happy and I can say I honestly can't blame him.

I don't want to lose him, he's my best friend and honestly I didn't feel free till I met him.

What can I do to save my relationship?
