For a while now I have been wanting to leave my significant other other for many reasons he dose not help with the kids at all and he is un employed I’m am struggling financially and physically I do all the cooking and all the cleaning I am the only one who feeds our child and he constantly puts me down calls me names tells me I’m useless and stupid and now he is starting to get physical pushing me and trying to choke me and saying things like I wish someone would hit you when I say he’s bing abusive and saying he wishes someone would k*ll me ik I need to leave but I’m broke nad I don’t have a car or license and we’re are living with his family atm so I really have no wear to turn and there is no way I’ll let my baby’s be on the street so I have no clue what to do I just want out atp
