My friend, who I’ve know since we were 10, always asks me for advice but never takes it - in fact does the opposite. Some prominent examples:
Asks me if she should have a baby with her boyfriend she has only known for a few weeks and is showing signs of controlling behaviour. I say no, it wouldn’t be fair on you or the baby. Gets pregnant anyway and lo and behold the guy becomes abusive and controlling.
Asks me what last name to give the baby. I say hers or double barrel, given the child’s father is abusive and said he doesn’t want the baby. She gives the baby his last name anyway which has since caused issues, as I predicted it would.
Asks whether or not to open a joint banking account with her abusive DP. I say I think that would be a stupid idea. She does it anyway and he steals her money and locks her out of the account.
And today she tells me she is back with her DP (having “ended” things with him at least a dozen times) and asked if I thought they should get a dog. I say it wouldn’t be a wise idea, as she is living hand to mouth as is and has a precarious living situation with her DC. I said I thought it would be selfish on the dog, as she doesn’t have the time to give it the attention it deserves and he definitely won’t take care of it. Messages me hours later saying they bought the puppy anyway 
There’s also loads of other situations that she’s asked my advice for and then ignores it.
I get she is an adult and is free to make her own decisions but AIBU to get pissed off that she always comes to me for advice and then ignores it? And then inevitably comes to me for comfort when her bad decisions create more problems.
What would you do in my situation?
Or am I just a boring, sanctimonious buzzkill?
