Search Results: sex bringing a couple together

So my buddy had a friends with benefits for like 2 years almost. They both had young kids that played together and they would hangout all the time. She would stay the night often, go to family events, basically everything a couple would do. He said that out of the 100's of times they had sex they only kissed during sex a handful of times. She knew he didn't want a relationship but being exclusive was brought up several times. One night they were on the way to his house after drinking she spoke up and basically said "Either we date or I'm gone". He said repeatedly that he didn't want to which led to an argument. Long story short he kicked her out that night and in a rage she called the police claiming domestic violence. He was arrested and put in jail overnight then released cause it was a false claim. She would try to contact him saying she's sorry and stuff but he wouldn't reply. Like 6 months later he said he finally replied and They ended up sleeping together. He said that she was so upset it all happened and she couldn't have apologized more. They now talk and have sex often again. He is moving into an apartment and she was also looking to move. He found one that was really nice and told her about it, now she is highly considering moving into the same apt, different building. He must like her seeing all that happened and he is talking to her.
My question is, Is he an idiot for talking to her? Is her moving that close a terrible idea? If they did do you think she would want more that friends with benefits like before and the same thing would happen?
