lesbian and in the closet with a husband

So I'm 19, married , and an in the closet lesbian. I have one son who's 1 year old . I love my husband on an emotional level but not in anyway sexual . I can't leave him because I love him so much and don't want to hurt him , but at the same time I'm not at all attracted to him and I'm attracted to women ! Is anyone else in the same situation or similar?
