don't know what to do

I'm not really looking for like backlash or anything I just need to get stuff off my chest but me and my man have been dating for more then 2 years we have a 6 month daughter and I might be pregnant now.me and him just broke up a few days ago over a lot of problems we been having. and I was completely compared for him to change my mind when we were talking about it but instead he threatened his own life because I wanted to take a break and was talking pretty much all crazy and not thinking of our daughter ... he even went so far as to say "can can always find her a new dad" and at this point I'm just really lost and feel like everything is crumbling.
