I wud say do not hurry in to it........she is ur wife now, so u have big time on ur hand.......let her njoi the new relationship n along with tht u can slowly push in ur liking for lift n carry........make her feel comfortable with u.make her like u more.....n automatically she will keep doing wht u like, evn whn u dnt ask her.......n ya do nt keep pestering her........jess keep it cool, I wud suggest u lifting her for time being n have fun..........n ya its better tht she puts on weight, coz at 70 u r normal weight........anything lesser than this will be gud for lifts bt bad for u lol.........so try out diff n funny ways of getting lift rather than directly askin her......or she may feel tht thts the only thing u want 4m her......n I have seen 4m past exp tht gals do put on weight during 1st few months of marriage

n u knw y.........so keep it slow bt steady n make it enjoyable ride for both of u
