Erm, I'm not so sure that accusing these women of being needy is the kind of help the op needs.
It would seem to me that in general a woman wants to have a relationship with someone whom she feels cares about her. You may have adored these women, however, they were not seeing or feeling evidence of your affection.
It can be a simple, semingly insignificant thing which can make a woman feel adored. I like it when i catch the guy i like looking at me and i can see the affection in his eyes. It could be touching her hand lightly, or holding hands. Give her a hug when you see her. Text her out of the blue and ask her how her day went. Write her a love letter and post it to her, she gets a nice surprise in the mail. Ok now i'm getting into the realms of a bit over the top.
What you really need to do is be there when she needs you. If she wants some help with something, be there, dont forget. Make arrangements to spend time with her, dont let it always be her who has to make the effort to arrange to get together. Listen to her when she wants to tell you something, even if its boring, dignify her by letting her see that what she had to say and her presence is important to you. All you have to do is listen, hold her from time to time, sit with her with your arm around her.
