An exgirlfriend called me up after 5 years and says she doesn't know why she dumped me, she misses me, and...?

she's got a boyfriend and a 4 month old daughter. Her daughter is named Lily, the name our daughter would have had if we were still together. She "cheated" on her boyfriend out of "necessity." Which means she made a poor decision, ended up in a place she shouldn't have been and couldn't get out of, rented a hotel room with a man she's never met, and was raped. She gave me money 5 years ago which she apparently obtained through defrauding a bank. Her boyfriend is a looser, they're living with his mom and sister. She just got fired from her job. But she's finally taking responsibility for her actions by seeing a psychiatrist, psychologist, and taking her medications. She wants us to be friends, what would you do in my situation? I'm thinking about just not talking to her anymore.
