No longer sexually attracted to my husband

My husband & I have been together for 3 years.. he is my first and only love. I used to be so sexually attracted to him.. we even used to have sex every single day. But for the past year I just don't ever want to have sex with him.. he doesn't ever turn me on and I feel so bad about it. I do find him very handsome still, and I'm still very much in love with him and couldn't see myself with anyone else. I honestly don't know what's wrong with me.. maybe it's because I'm not happy and confident with myself anymore.. I don't know what to do.. I don't talk to him about any of this.. I don't know what to do.. has anyone else been through something like this? (Also just had a baby 2 months ago)
