Is it possible for a man to get divorced twice and both be the woman's fault?

I've been seeing this guy. It's been a month and we aren't officially or anything. I knew he had been divorced twice which he's not even 30 yet so I thought that was strange. I asked about his ex-wives and he kind of nervously laughed and just said he chose wrong twice. I asked what was wrong and he confessed he used to date way older and he knows now that it was due to his mommy issues but his first wife he said was actually his foster mom's sister! He was 16 and she was 27 when they started dating which is legal here for some odd reason. As long as you are 16 you can date and have sex with however old you are. He ended up getting kicked out of his foster home for it and he moved in with her. They got married at 18 and 30 and divorced a year later because she was crazy. He met someone when he had just turned 21 and she was 43 and they got married a year later and then divorced after 2 year. I'm actually the only woman he's been with that was his age. And he showed me pictures of his ex wife and they are clearly much older. The one with his first wife just made me uncomfortable because he clearly looks like a child. I'm 27 and would never. All he said about his second wife is she was very financially abusive. I can believe the first wife story because honestly regardless she had no business being with a minor. With the second wife he wasn't a minor though and yes 43 and 21 is a weird age gap but is it possible he's just using her age so he can say he didn't do anything wrong. I'm a daughter of a mother who was married 6x and if there is something I've learned it's that if you have multiple divorced it's probably you. Just I've never been married. I'm not sure if anyone here has had multiple divorces and if so would you say you were at fault or you just chose wrong twice? Is it possible to marry wrong twice.

@Rachel I get that. I just don't understand how someone can fuck up twice. I just would assume when someone puts you through something bad wouldn't you be extra alert on red flags? I have dated a jerk before and I do everything in my power to never date someone like him again.
