Did he really break up with me because I wouldn't let him move in?

My ex broke up with me because I wouldn't let him stay with me after a month of dating.. he's upset because he has to work longer hours and find housing.. 🙄.. I have my kids here and wouldn't let a man live with me unless we were exclusive and getting married... so he ended things with me because of this and I asked for sometime fo myself after being in college 40 hours and hearing him complain about his problems for a month... it was emotionally draining... I asked him how am I responsible for his life ar 45 years old?
