Will I ever know what its like for a man to love me?

I'm 32 and never been in a relationship, never been told I love you, never shared love with a man and whenever I have been honest about my feelings for a man always rejected. I'm told I'm very attractive, down to earth, caring funny and the first ones friends come to for advice. I had a breakdown over a year ago because of all this affecting my self esteem and constant heartache and now I am attracted to a man again I'm terrified of showing my feelings as he has been looking a lot and now today suddenly coldness I just feel like nothing will ever happen with any man. Should I just give up with him? He's 45 I'm 32 but look 25 he probably sees me as a piece of nothing. I'm so fed up and would like some advice please x
