@Sonjing Yes, sure! That will be too long to write as it was a lot of inner work, so I'll try to explain the basic.
I was kind of easy going, casual, not demanding, comfortable girl. I was attracting reasonable men, but as result - relations were the same as I was and was treated accordingly.
For starters you need clearly understand what you want. I wanted serious relations, which in some time will lead to marriage, family, kids.
Next - what kind of man you want. I wanted successful (means with good job/business and so on or at least man with good potential), smart, funny, strong, healthy, etc. man. Thats very important as believe me you dont want to end up having 2 jobs to pay debts of your alcoholic, who will tell you to go back to work in 3 weeks after you will deliver him a baby (true story for some women).
Where to find that man? Not at your home on the sofa its for sure. So I started actively going to gym, some courses/classes, travel, going out to nice places only and online (found there veeeery good guys. and lost them 
). My issue also was that I was having 1 date and after was sticking to that guy until it will be ended. I changed that - I had few dates a week with different men (nothing intimate, just dinner or coffee and no doubledating. You find the one you really like, cancel all the other dates). First date is a foundation for your relations. You make it as kind of interview to see if there can be future, no need to wait like "will see" or expect that things will change. So after filtering men according to what kind of men I wanted, I was asking mainly about his plans, values and expectations (e.g. doesnt want kids - good bye, doesnt want family - good bye, have no financial plan - good bye, he is 35 and didnt find himself yet - good bye, wants to move to India for 3 years to find his dzen - good bye, and so on. And many women might not agree, but wants to split the bill - good bye).
Next how you position yourself. However modern we are, men are still hunters and as more difficult to get you, more they afraid to loose you. So I'm not calling first, I'm not asking out, I'm not answering messages/calls at late evening/night, I'm not free on weekends, if we agree to have a call around 4pm, I wont answer if he calls at 5pm, if he is late for date more than 10 min without serious reason Im leaving. And like that until we will get serious.
Very important one - what men want/need? I was thinking about it a lot. So its not your education level, job, money you earn, exceptional beauty, not cooking, washing and cleaning. Ive seen some girls, who are ugly, short, work as waitresses and fantastic men are around them, who care about them, respect, love like crazy and can get the moon for them just to make them happy. So the conclusion: men dont love women for what women love men, men love how they feel themselves next to particular woman. OP was saying that she doesnt know what to offer to a man. What I was offering was "Look, I have this education, career, I'm so attractive and sexy, and independent, but I'm also very nice, I'll do everything for you and also everything instead of you because I'm very smart and know better". It was not always all together usually. Anyway, what man wants is to feel like a man, like a hero. He is "fighting" all day and when he is seeing you he wants to relax and get appreciation. Also he needs support and motivation.
For example (I will be exaggerating, but the idea will be clear):
- he brings flowers, very often as I heard the reaction is "beh, thanks. not needed"; he went to work, earned money, went to flower shop, chose flowers, spent money on them (instead of beer for himself) and brought to you, reaction should be "omg!omg!omg! what a beautiful flowers!i'm so happy!blahblah"; if you wont give him proper reaction, next time he will bring you nothing, next time you will split the bill, and next time he will go to that one who will be shining bright from those daisies.
- he is coming back from work and says "i got promotion", and you says "hehh, I got 2 promotions" or "ah ok"; he says "i signed awesome contract" and you "pfff i was signing such contracts in kindergarten". you have to "omg! im so proud of you! you are the best man in world!"
- he is coming back and says that he lost his business, you say "you are so smart, strong, blabla, you will fix it, i believe in you" (never ever ever offer money, be guarantor or involve yourself. and dont ever say "i knew it" or "you looser")
So you have to be inspiration and source of energy.
Also very important one and why some men leave - they get bored. You need to be "full" - have some interests which will give you drive. They shouldnt match with his, but when you talk about what you like to do and doing good, lets say you fry incredible pancakes, he should get hungry while you are talking. And nobody likes that kind of thing: "what are you doing?" - "nothing, just thinking about you"; you are not doing that ever, you are trying to make new smoothie or watching your favorite ballet.
All that is not a guarantee of success, there are exceptions, but such mindset will help you easier break up with asshole if will get involved.
It worked for me and it worked for many of my friends.
