Being true to yourself

Hey there, so this is me, asking advice, on finally coming out after years of hiding it and suppressing what is truly me. I am 35 years old and have known since high school my attraction for women is a real thing. However, I've never said anything to anyone until recently. I've told 3 of my closest friends and they have been nothing but supportive. I am, however, married, to the father of my two children, which puts me in quite a predicament. Staying true to my husband,  who I've been with for over 7 years, or be true to MYSELF and finally let myself become the person that I truly am.
