Help me find the courage 😞

I don’t want to leave my husband but i know i need to leave my husband. He’s had an emotional affair jus 2 weeks after our vows with an ex of his . I forgave him but of course it still hurt, it still hurt bc he never gave me the time i deserves to heal from it. The emotional affair that lasted the first 2 months of our marriage brought out more problems . He started to turn against me and was supposed to quit drinking but never did. We fought for months until we decided to separate. Then things seemed better after being apart for two months. He moved back in the trust was rebuilding and a few months later we even planned our 2nd baby. 2nd baby is on its way and the drinking has continued my husband STILL continues to lie to my face still continues to hide his addiction i always try and believe things will get better bc we have so many good times but once i catch him lying Again all my hope just goes out the window. I feel completely defeated 😕 i don’t want to raise two kids on my own where do i even begin to start? No child care in my state unless the kids father is on child support. Can you put your husband on child support without a divorce case going on ? I just don’t know i feel stuck. I’m

Tired of fighting i fear for my children growing up without a dad but i fear more for them seeing him and catching on to his ways of being under the influence.... judge me if you feel so i just needed to tell someone how i feel :(
