i don't think im in love with him

he's my bestfriend I care about him I love him but I don't think either one of use likes the thought that this whole thing should of just been us hanging out our sex life is none existence and when I think about having sex with him it's like great fun looking forward to it searching for ways to get out of it he does to he's to tired for it from work even if it's been a month I'm sad at the thought of losing a wonderful person out of my life I really want to see him and have in my heart like I should we are supposed to be starting a family not breaking up
