OLDER WOMAN VS YOUNGER MAN

MY LITTLE BRO IS 18 AND IS CURRENTLY DATING A WOMAN WHO IS 28 I TOLD HIM THAT THE AGE DIFFERENCE IS WAY TO MUCH, BUT HE DOEST CARE!!! SHE SPOILS HIM BUYIN CLOTHES AND TENNIS SHOES. THE LADY IS NICE BUT I JUST DONT KNOW WHAT SHE SEES IN MY LITTLE BRO I TOLD HIM THE ONLY REASON HE LIKES HER IS BECAUSE SHE SPENDS HER MONEY. I JUST DONT WANT MY BRO TO GET TRAPED OR HURT. SO MY QUESTION IS WHAT ADVICE SHOULD I GIVE HIM? IM JUST TRYNA LOOK OUT FOR MY FAM. GUYS WHOULD YOU DATE A WOMAN 5-10 YRS OLDER OR IS THAT JUST TO MUCH?

I know i'm not one of the fellas, but i just wanted to say "THAT IS TRIFE" okay........im leaving now :???:

yea i'm wit u i wouldn't think it was love or anything but yea i'd do it i mean being bought stuff the whole her being older it would make me feel good
