Divorced man - pictures on facebook and me getting annoyed?

i've been with a man for over 2 months now who has been keen for it to be a 'relationship' and told me very quickly he loved me. in the last month especially he's grown on me, we really get on and i'd like to make a go of it. this might sound stupid but this is what's bugging me...he's getting divorced (him and his ex wife are a bit older) and she lied to him a lot about money and left him in a mess (she suffers from bipolar disorder) and his family and friends are very against her. because i've not been anywhere near a married man before i feel odd about it. (they haven't had contact for 8 months and they wouldn't get back together) but what makes me feel weird especially is he's got loads and loads of albums on facebook with her in, in her bikini and stuff and of them as a couple. i use this thing a lot to communicate with my friends and he's now meeting my friends and adding them. i have said to him many times i don't like them (or me) being able to see photos of him and his ex wife together and can he take them down (she are not yet divorced - it takes about 10 weeks to go thro) but he doesn't. or maybe forgets and doesn't think it's important. it's now really really winding me up. i'm thinking of making my point by taking him off there as a friend then when he asks why saying he should give me a shout when the divorce has gone thro and he's ready to take his photos down as i've now mentioned it four times calmly and subtly. i know it's that he's just being lazy and has forgotten but i am pissed off it's got to the stage where i have to ask him outright or put up with it. i know this isn't a *big* problem and i know it's a bit immature of me to be bothered..but what do people think....??
