i used to have the same problem when i worked at supermarket, there was this geeza that worked there 2 we got on well, he was no oil painting we got on well, dont get me wrong he was really nice to me, but i started dreaming bout me 2 so when he suggested we started seeing eachother i couldnt bring myself to do it, cos iknow i wouldnt of stayed with him, i would just see this man as a friend, u may regret it if u decided to take things further, oh and dont wreck ur marriage just cos u get butterflies it aint worth it
