At this point maybe she should be looking at what she has to offer someone else as opposed to what others can offer her. I do not think I have to point out what the common denominator is here
Oh Huni.... Just relax and stop worrying about it... Women (or men) are not attracted to desperate and clingy. Just go with the flow, be yourself and trust me when I tell u it will happen when u least expect it and or not hunting people down like a panther and slowly sucking the life out of them out of emotional hunger;)
To answer your question; yeah, it's completely normal at age 30 to have nothing worked out. And no, none of that shit had anything to do with feminism.
I have been thinking the same thoughts over the past year, after my last relationship ended. My mental and emotional state are much better now, it took some time, but I am actually enjoying being single now. I'm in no rush to find love and have another relationship. What you wrote, I can relate to...and I'm a man. Too bad this place is anonymous, I would like to buy you a coffee, take a walk and talk. Good luck to you... :)
