How can I give him the signal that I like him :) ?

I know he likes me and I like him too... but he is too shy to make a move, even though he is over 35.. he has some traumatic experience due to the previous relationships and marriage, so he takes his time to make a move. But I have deep feelings for him, we have known each other for 4 years. But we became friends 7 months ago and I started developing feelings for him. I can easily communicate with him, he never makes me feel alienated, he is always so sincere and friendly towards me. I would like to take the courage to show him I have feelings for him without creeping him. Can you help me please? :)
