That is a very clear statement for him to say. It sounds to me like he is struggling financially and doesn’t know how to use words to tell you. Therefore, he has used an ultimatum to clarify his concerns with you. His time frame is likely for you to meet if you decide he does need your help financially. Perhaps the two of you need to have a discussion about your finances. I do believe you may be able to come to a mutual understanding if your approach is handled delicately.
