He definitely drinks. Yet I am the one who ended up with a DWI before the pregnancy

The entire situation was disturbing. He calls me to see if I am okay, then I text him after my anatomy scan only to have him threaten me with the police if I text him again. He calls me this morning (he sounded manic) saying he loved me and wanted to take me out. Then he makes me buy him coffee and wont respond to texts.

I think he needs medication to level himself out, and he is not getting treated so his behavior becomes more and more bizarre.
