My dilemma,

I see him every day and every day my feelings go through the roof for him, I wasn't too sure whether he noticed me, I've started wearing tighter clothes, wearing a T-shirt with no bra and a very short skirt, leaving my dressing gown loosely tied up wearing nothing under there except my panties, smiling at him every morning,, Should I be the 1st to make the move? Would it spoil our friendship? I live in bed at night thinking of him being here by the side of him since my husband died 10 years ago I've not had many men in my bed, how can I get him into my bed?
