Being a leo's (police officers) girlfriend is HARD

My boyfriend works very long hours and he is barely ever home.. i love him and support his career of being a leo but wheres my support?. I asked him if he wanted to go to dinner sunday? He said "oh i have training from 4pm-7am" like i honestly cried... i just want him i feel like im failing him. Im so sad. Im busy too with the kids working 2 jobs and going to.school... but feels like its never enough.... I need SUPPORT PLEASE
