Who is 2 blame for all of this?

My 45 year old aunt has been dealing with an older man in his 50's 4 the past 2 years. The man is divorced with 5 kids. He keeps in contact with 2 much younger, better looking ex girlfriends who are 26 and 34. My aunt has even met these women quite a few times. She wants this man 2 marry her or at the very least commit 2 her but he wont. She came 2 find out that the man lied about several things concerning these women. He also hid several things. In July 2013 she had a nervous break down and was in the nut house for over a week. She is trying so hard 2 get the man 2 cut these women off and settle down with her. Im so tired of hearing a new story every single week about this man and these women. Shouldnt she just accept him as he is or move on?
