My best friend has been single for a while after leaving a loveless marriage.
Around eight months ago she met a man on a night out and started dating him. Roughly three months ago she found out he was living with his long-term partner and she'd unknowingly been the other woman, nights when he stayed over at hers his partner thought he was away with work. He told her that the relationship has been over for years, that they're only living together for the sake of the children and that she's the one he wants to be with. To prove his commitment he proposed to her and moved in with her that same week. The wedding was quickly booked and is next month. Friend has paid for the whole thing, he has paid nothing.
I'm weary of him because of how fast he's moved, the cynical me says he proposed and moved in because his partner kicked him out and he needed somewhere to go, however he is very outwardly charming and my friend is smitten with him.
He wants to open a joint bank account for them both to pay their salaries into and she was in two minds about it. During a conversation about it she said that he's not paying anything towards her mortgage or bills despite living there. When she raised this with him he got really defensive about it and said he can't afford to because he's sending "all" of his money to his ex-partner as maintenance for their children.
Her four year old accidentally called him daddy a few weeks ago so now he's really pushing this and encouraging both of her DC to call him dad. He keeps reminding my friend to "back me up" on it and gets huffy if she refers to him by name to the DC rather than as dad. Another thing that is weirding me out is that he will often tell "funny" stories (funny to him) about the DC walking in on them or almost walking in on them.
He goes everywhere with her and I mean everywhere, whether he is invited or not. A few of us meet up at least once a week and he comes along. If we go on a night out, he's there. Trip to the cinema, he's there. Take the DC to the park, he comes along. She pops in for a cuppa and he's there too. I have no issue with spending time with my friends as couples but it is all of the damn time. When he comes along he either sits off to one side and doesn't engage much or else sits there hanging onto her hand, whispering in her ear and trying to neck on with her. The few times she has come out without him he has messaged her constantly and she's ended up leaving early.
He regularly gives her the silent treatment over complete non-issues such as her buying a pair of shoes she saw and liked or deciding to make chicken for dinner when she'd previously said it was going to be pasta or trying to talk to him while he was watching TV, colouring her hair after "I thought we agreed" she wouldn't, absolute nothing issues but he makes them into a huge deal. He then "apologises" with over the top romantic gestures but no actual apology.
There are so many red flags and I think she sometimes sees them too because she'll say things to me like she's sick of not knowing which version of him she's going to get on any given day or that her head is spinning from how quickly he changes or that she's skint from funding everything but then the next he's done something incredibly thoughtful and romantic and spun her a semi-plausible excuse for his behaviour so she's head over heels again and saying how lucky she is to have him.
When he does the things that upset her I point out to her that she doesn't have to accept it and that she is worth more than this, that she doesn't need him, and I highlight what he's done and why it's shitty but I haven't actually come out and said bluntly that I think he's abusing her, at the least emotionally if not also financially. I'm worried it'll escalate especially once they're married but I feel like I need to tread carefully as he is the type who would use me saying this to prove that everyone is against them and will try to cut her friends out to isolate her even further as then he's got her to himself.
How do I help her to see that he's a cunt and how do I raise these worries with her? I'm supposed to be a bridesmaid at the wedding when all I really want to do is stuff her into my car and drive her as far away from that altar as possible.
