My fiance (we had nikah but not  legal marriage) has been going through some financial difficulties for some time and has been taking money from me. We want to get married legally but cant do so until he is financially stable. For the past 18 months, I have been giving him money to survive for basic things, food, rent etc. If I dont give him, he will be homeless. But I am tired and dont want to continue this anymore. I am scared that he will become homeless and wont be able to eat. Is there an Islamic responsibility for me to take care of him? He tries to work but has no qualifications and cant get a decent job that supports him well enough. 
I dont know what to do. Is it immoral to walk away from him and leave to fix himself? 
Thanks and please be kind.
