Hi, Tiffany. Welcome.
Sure sounds like your SO has a problem with drinking and, possibly, gambling/overspending.
Have you been to Al-Anon meetings?
I found them to be a great source of support, and going helped me to clarify my thinking.
As Lexie stated above, unless your SO becomes sober and pursues recovery, things will likely get worse, as alcohol addiction is progressive.
Nothing needs to happen today, but I would recommend learning as much as you can about alcohol addiction, if you haven't already.
I would also think hard about what kind of life you want for yourself and your daughter.
Life with any kind of addict is a hard road. I wouldn't wish it on anyone.
