Fiancee' lookin a more lately?

My fiancee be lookin at more now den ever, mostlyda same nude stars wit out da men, n i saw pictures of gurls gettin nasty stuff done like loads to dey faces. I found it on his computer. He says he only do it when I'm not home and I could tell by his history dat he tellin da truth. He said he look at it more now caz he more stressed out n den feel more lonely when i aint him n it just a way to get off. But I gave him naked pics of me before why cant he use dem if he dont u dem if he love me n dont wanna be wit other gurls? We been together for 4 years now n we have a kid together. The thing it tho is dat I aint no frumpy house wife, I been hittin the gym n look better den ever before we even met n he even be gettin jealous sometimes when I be gettin hit on more den ever. I'm just confused, am I lackin somethin? He says no i takin it too seriously. But Im hurt caz he aint ever gonna do some of the **** he was lookin at in dem pics to me, i have way too much respect for mahself. N some the gurls were dressed in weird costumes like dogs n cats n actin like dem animals in videos. Does he want me to do stuff like dat? It aint like regular wit guy n girl humpin. No guy ever in da stuff he be lookin at. One more thing, I been sayin for all 4 years dat i want implants when i get da money n he always be sayin no you look good da way you r baby n dey a waste of ur money. But after I saw da on his history right under it was information n pictures of implants so he was lookin up job after he saw da . I asked him n he said he was jus educatin himself on somethin i want done to support me. But why look it up after gettin done seein naked chicks?! is he startin to see me as not good enough now and now thinks i shud get da after seein porn stars wit dem? Please give me some insight, guys, girls, ne one who been here n what dey out come was? It tearin me apart, i cant even look at him da same.
