A confusion

Hi. I have been single 4 years. I have worked on my personal growth and now want to move on and date but I don't seem to have much time or energy. Apart from that I have had some bad experiences in relationships including abuse and so I am wary and have trust issues. But I don't want to live out the rest of my life alone. I feel I have given myself enough time. Also I like someone a lot but its a difficult situation as he just broke up with someone else. My friend says to let him come to me if he wants to. But he doesn't know how I feel about him at all although I guess there is an attraction between us. I just don't know where to go from here. Thanks.
