Money from older man?

So I'm eighteen years old. I have a fine from missing school two years ago. In all it was 700 some dollars. I got it down to like 200 range. At this point in time i was desperate. My family shut me out. I offered to do work for them and they turned me down knowing there was a warrant pending for me. They said they'd take me to job interviews (already a tough time finding jobs where i am) and they cancelled last minute. And ended up deleting the job interview numbers so i couldn't ask to reschedule. Now, i have been in a relationship for over two years. But we've been fighting and not talking much. He hasn't really helped me out either. I needed to stay in his area for a few days so i could get money and work and he sent me home cause we were fighting. So this older man (late 30s) my exs dad offered to pay. He was my last resort because no one else wanted to help me. He literally picked me up gave me a hundred dollars to pay it and took me home. He asked for no favors. I kept asking if he needed anything but he already knew i couldn't give him what he wanted. He wanted a woman. In the past my boyfriend didn't want me accepting money from him. Idk wether to tell my boyfriend or keep it to myself.
