Scared of love.

So I have been dating a guy on and off for the past 7 months. And I keep pushing him away because I'm scared of love. Due to an ex boyfriend who hurt me mentally, physically, and emotionally. And I told him my boyfriend this.  He said he doesn't want me to hurt myself or him.. Please tell me how to fix my insecurity on men!! I really do love and care about him so much😭.
