Boyfriend causing me to indirectly feel insecure?

My bf is really high achieving - and he work's so hard to get what he wants and he always gets what he wants. He also wants the best out of everything that he has in his life, including an amazing girlfriend, with a 4.0 GPA, with international experience, open mindedness, looks, smartness - everything in one. He doesn't verbally say this to me, but I feel that I know that that's what he expects of his girl.

I feel really really insecure because I feel that I am not yet what he has described to be his dream girl. Sometimes I feel lost, and I find so many ways to make my self achieve something so that my credentials will be increased in my peers. Sometimes, I feel like I have to put on a mask of being this person who is amazing with amazing credential but i feel tired because I feel that it's not really me. I feel that If I dont put this mask on, he will think less of me and won't like me very much if he knows that deep inside I am as insecure as any other people.

Is this normal? How do I get rid of this feeling because I tried everything and it still persists! I even tried christianity. FYI: my dad always felt that my mother wasn't good enough in her life credentials and I know that this is an underlying issue from when I was little. I still feel that up until now that I have to work very hard in my career my anybody to truly love me and want to genuinely love me. And I feel that way towards my boyfriend now. Worst thing is, the more I feel it, the more I think about it, the more that it's stopping me from achieving the life goals in my life.

Is he making me insecure? or is it my own feelings? I can't differentiate it.

I know this is not normal - what do I do to fix this? I feel like i'm trying so hard I have forgotten who I am.

Your advice will be much appreciated.
