Welcome to PC. Being in love and dependent upon someone in active alcoholism is definitely challenging and difficult. There are some resources for you to seek out, specifically Al-Anon
Welcome to Al-Anon Family Groups where you will find others who have been there and have in many cases found good solutions.
I will say from some experience with this issue, that I had to stop putting any energy into supporting and helping the alcoholic, and place all of my time into protecting myself and my child. I had to start with practical needs like shelter, food, and healthcare. Instead of depending on others, I had to change my approach to life and fend for myself. In the end, I am much stronger.
Good luck to you, and let me know if I can help. Thanks,
