Boyfriend advice please?!?

Hello: just had a question> I have been going with my boyfriend for 6 months and when I first met lhim i thought he was divorced. then after a couple of months i found out he was only separated. I broke off with him for about a week because his ex girlfriend was at his house when I came over un announced. He says to this day that he is just friends with her. I don't beleive in that. If you broke off with your ex, then why still be friends. He doesn not have any kids with her, so WTF. But my question is really that he always wants me to remind him to get dicvorced. he wants me to pressure him, etc, so he says. My thing is why do I have to do this? Is ths just a cop out? What does the community say on this?
