Should we trust women's in their late twenties and in their thirties who are single and when you talk to them they seem so "lovingly" and "nice" and they say they care the most about love?

I could say for myself that for a long time I was that "nice guy" who always end up in the friend zone. I've been through all that and I've changed a lot in the past several years. And learning more about women I'm now very skeptical and don't trust them as much I used to; now I'm always looking to see what's "behind the curtain" when I'm talking to them.

I kinda don't trust them when I talk to them and they seem to lovingly and nice, and they say that all they care is to be loved by a man and that they want to share her love with other man.
