He doesn’t have money for rent

Ladies, I’m stressed. So i let my boyfriend move back in with me again and rent is right around the corner and he doesn’t have the money.. this is why I kicked him out the first time.. rent is $835 i have my half... and being that he said he’ll have his half I used the extra I had left over to get things needed and put towards other bills. He doesn’t have his half he saying he has to pay his carnote and it won’t be enough so now I’m short on rent... i feel he’s lying. It’s always an excuse. I just don’t know what to do because i feel like it’s the same cycle. And I always told myself if im going to struggle I’ll struggle by myself. I also may be pregnant I’ll take the test in the next week or so. I’ve been handling my own rent and stuff but being that we agreed to work things out and start over i asked him to come back. I’m overwhelmed and i feel I can’t take his word. He helps cleans, he cooks for me and stuff.. he brings food from his job.. he’s sweet. His temporary car tag expires tomorrow I’ve told him twice about it to go check the Mail at his family house and get it so he doesn’t get pulled over and he hasn’t did shit but say Okay. He works a part time job cause he lost his other job but i don’t think he had the other job to begin with. I love him though...
