Pil both hate each other. Although fil is slightly more restrained in his expression on the subject.
Mil has already made a comment about not wanting to be in same room as him on wedding day.
Perhaps we actually SHOULD elope!
It's the reason dh and unjust fucked off without telling anyone. My mam and dad hate each other, dhs mam and dad are iffy and then my lot won't like dhs lot. All the fucked up family dynamics mixed with alcohol, I'd not have had a good day, plus I hate any attention on me, and hate having photo taken, wouldn't change a thing we did.
I'd have like my Mum there but we couldn't do that without losing everyone off, funnily enough, my Mum was the only who wasn't oissed off that we married in secret because she exactly what a twat my Dad could be and that he wouldn't behave and him and stepmum would goad her (he has form) and my mum was happy as long as I was happy. Mil and my step mum were furious though! Their reaction just confirmed we'd made right choice, any wedding would have been about them and how they wanted things etc etc.
I didn't want any gifts from anyone, we'd been together for years and had dd and everything we needed, but mil linked the lack of invite to a lack of gift and said so herself. Stepmum gave me £50 cheque and said its less than my db got as she never got to attend and have meal etc, I never cashed the cheque btw. If a gift has strings attached then it's not a gift.
If you flip it around, no money expects but the Inkaws have paid but your parents haven't for whatever reason, would you then question why they haven't? Would you take it as a sign your mum didn't care about you? Would you struggle to treat them equally on the actual day? I dint think you are grabby but I do wonder if you'd be worrying if they cared for you if it was your parents or none that had contributed and why if you genuinely didn't expect any money from anyone, it's bothering you that mil and FIL haven't offered.
Honestly, use it as a positive, as if there's a weird dynamic going on (which is what I think is bothering you more than lack of offer if that makes sense) and they are trying to make some weird point, then she's done you a favour as she can't make digs in years to come about how your wedding couldn't have happened without her, can't emotionally guilt you with things like "after all the help we gave you ......" it can't be thrown back at you in the future.
My dad didn't offer anything to my brothers wedding, he told them that sits dad should stump it all because "tradition" it was a small but fancy wedding which my db and sil had saved for for years, Dad could have contributed easily but didn't all fin apart from he constantly grilled them about how much his mil had put in, or how much our mam had put in which db and sil refused to answer. He'd sit and say my should be doing a b and c, while offering nothing himself. Dad wanted a suit to match wedding Party, and was annoyed when my db said he'd have to pay for it himself, he thought sils dad pay it for him, lots of demands from Dad on how step mum better be in more photos than our mum, about how dad better be sat closer to them than mum. He almost ruined the whole day demanding to make a speech to thank everyone for coming blah blah, db said no, his FIL is doing it as its "tradition", pissed Dad off and he was stomping about the place slagging my mum off, calling db ungreatful after everything's he's done for him growing up, and just making it known he was pissed off and acting hurt and it's not fair that brides dad can do speech but he can't. He got his way in the end, as always. The inlaws knew what my dad was like and were lovely and sat at the back with my mum and I, I dint know how much they helped with money, or even if they did at all as its was never brought up, as it shouldn't be. But my dad expected to be treat as if he'd funded the whole thing at the wedding so I get the equal footing thing if you meant it in that way, rather than a they get less food and wine type thing :)
I'd try to stop letting mils comments get to you too and work on how you react to them as there will be many to come in future, and from reading posts on here, they get worse when grandchildren come, (which I hope they do for you). I guess I'm saying as long as you and dp are happy, then it doesn't matter and learn to bite your tongue :)
