<human>: My live in boyfriend and father of our son has been angry and throwing things recently. He never throws things directly at us however. I've suspected he's been depressed and I setup counseling that he chose not to attend. 

I found needles in an area of the house (the baby has no access to this area). I confronted him and he said they were for body building. I believed him but I opened a drawer and saw strange drugs postmarked from another country. 

Sometimes he's sweet and apologizes for making me cry. I'm extremely torn because I would prefer our son to have his dad around if possible. 

Most days he stays away from the area of the house we are in and he stays up all night playing video games in the same area I found the needles. Then he sleeps all day saying he is exhausted from work. He rarely talks to me except in two to three word increments. He has refused to communicate saying the more I ask him to talk, the less he wants to. 

I've begged him to get help from a physician or a therapist but he says it won't help. Has this ever happened to any of you? What would you do/what do you think I can do to help the situation? Please consider that we have a baby when answering.

Can you condense the text into a few key points?
<bot>: Live in boyfriend and father of my son is angry and distant. He throws things, leaves house unexpectedly, rarely interacts, and I found needles of unknown use in home. What would you do?
