My aunt tried to comitt suicide

I hesitate it about posting the update on my aunt, the reason is because I'm angry and at the same time sad, but here it is:
I was Instant messaging my sister last night and she told me that auntie V didn't come home one day after her therapy, of course my mom is fraking out because auntie is not very familiar with that city. Auntie calls a few hours later and tells my mom that she is back with her husband and that she is in her house. She explained her that he waited for her outside my mom's house and asked my aunt for a second chance he told her that the mistress thing was a "set up". He is a lawyer and he is on the bad guys side all the time his mentallity is that the bad guys are the ones with money(the tipy of bad guys that he takes are wealthy crooks)one day he had the case of a one of those people and he lost the case therefore the bad guy got really angry b/c he was sent to jail and he told him that he was going to seek revenge(all this happens in Mexico where laws are diffrent than here) and getting someone to go to his house to tell all those things to my aunt was his revenge, I don't believe a single word of that BS story but obviously she did that is way she is back with him, but the story doesn't end there. They are adopting a child now!!!They never did it before and they've been married 17 years or so, he never wanted to adopt, now they just brought the kid home this week.
These are my reason why I feel sad and angry.
1.- He never went to visit her when she was in the hospital
2.- I think he doesn't want to divorce her b/c of the money issue
3.-I'm very dissapointed because she doesn't see how much pain she caused to all the family.
4.- she is very obssess with a child. I don't have kids and I don't think I'm ready to have a child althoug I've been married for 5 years, why can someone be so obssess about becoming a mother?
5.- She didn't care about the help my mom offered her, she just trashed everything that the therapist and the Psychiatris where working on her.
6.- Is not that she has been happy with the guy for the last years of her marriage, so what is she trying to work out?
7.- In a way she attempted to killed herself because of him!!!
Am I overreacting? please ladies tell me. It really hurts me that she is acting this way.
Today is her B-day and I'm not calling her, I supported her after her suicide attempt, but I'm not supporting her on this. I feel llike is a slap in the face to the whole family.
I'm sorry for the long update.
