Have been a lurker here for a while but had to comment on this car crash. No emotionally intelligent, self respecting man in his 30s/40s is going to jump into a marriage with someone recently divorced with kids.He must be desperate to be married, as is she - or they'd have been happy to take their time before rushing into it. They both love the idea of 'sticking it to society' but society will stop caring at some point and they'll be stuck with each other. She talks about how she knows herself better at 43, and it's like but you don't know yourself without a man! And you also don't know him because you've never seen him with your girls or seen him outside of exciting date mode. Being 43 means you learn to be measured and differentiate between limerance and lasting love.
On a more sinister note my husband is a police officer who's seen his share of sexual and domestic abuse maintains that men who very quickly marry women with young daughters can be predators. Because they know the mother is so eager to be married, she's likely to turn a blind eye or have poor judgement. Even if they're not that scummy, it shows a lack of boundaries for the daughter's comfort and safety - you want to get to know them, have them be comfortable with you before presenting as step dad. They're kids, everything is exciting, it's a parent's job to manage the risks for them. She's so blinded by the lifestyle she thinks she'll have with him after the disappointment with Matt, she doesn't notice that a truly successful man will be more cautious about financial commitments. Unless he's a predator.

I also don't think he'll really marry her... Is just doing it to get his own profile out there and will bail once he finds someone else. Or the reality sinks in. If he does marry her, he's a walking red flag.
