<human>: Provide a brief overview of the text.

My boyfriend today told me that his ex girlfriend's status in his life—with whom he had spent 3 years or so—is much more serious than mine in his life. He continued that this is a result of us being in a long distance relationship and only 5 month length versus theirs had been in close proximity and much longer. 

He had told me that he wanted to have children with her, and that he had been worried whether his family would accept his low income job or not. He however, stated several times that he does not want to have a child with me unless I would take care of that child by myself. This caused me to feel that there is a difference and I am posited below her in his mind. I pushed him today and he approved my suspicions. I told him that I no longer desire to stay with him. He however, did not find that fair and protested my choice and even tried to make me feel guilty. I broke up. But the question is: was I right to leave someone for such a discussion? I am also curious to ask guys why a man would desire to keep a relationship with a woman whose relationship has a lower status for him than the previous one. Why doesn't he try to go find someone who is close to him and can make him feel the same way that the previous one made him feel?
<bot>: Am I right to leave someone when I have learned that I occupy a lower position in their life than their ex? Or should I consider to accept their justification of long-distance and short-length of our relationship for the existing difference?
