What's next?

I came out to my husband of 12 years yesterday that I am bisexual. I haven't ever told anyone else not close family or friends. In all honesty ive never acted on it either. I've only ever dated cis men. I also got married and had kids pretty young I was 22. I'm sick of hiding who I am. My husband took the news amazingly and even said he had a feeling that I was bi. I've never told my close family and friends because I just felt so alone in it. I remember my cousin coming out as bi and my mother saying that she was so glad her children are not like that. She believes you can just be straight, lesbian, or gay. She said a person who is bi is just confused on what they want. That was 10 years ago. I'm now 33 and really finding out who I am and I don't want to hide anymore. I feel my mother has also really grown since those words being said so long ago. Please don't take what I said about her badly she is an amazing person and has learned better since then. I feel its ok to come out now. My children are getting older as well and I want to be an example to them that its ok to be who you really are. I've never done this before and i'm scared. Are there any books, websites, advice you can give me? In my mind I keep thinking is there really a point in telling anyone this? I mean I'm in a monogamous relationship and have kids which is what works best for me. No disrespect for others that practice different.
