How do I stop being rejected by women all the time ?

Obviously you need to make adjustments in the way you come across. I can't be more specific with you because I don't know you and have no idea why you're being rejected so often. Perhaps you could elaborate?

One way is to stop asking them.  If you don't ask you won't be rejected.  Simple.  Indeed if you treat them as human beings sooner or later some of them will let you know if they are interested and you won't even HAVE to ask.  Let alone face rejection.

Stop assuming that women want what men want.
We are not men, but if you pursue us the way you wish we pursued you .. we will flee you as surely as the deer flees the hunter.

Women are natural whores so just pull out a big wad of money, they will all respond.

Get a hooker for sex. Women are overrated dude. 

I'm 39 and have never had a girlfriend.

What I've frequently been told is to not "try too hard" or go overboard and not be natural. 

That may sound vague and ambiguous, but it's also simple. 

I don't know why its happening, but here are a few ground rules to follow:

1. Treat women as dignified people, not objects.  
2. Be a gentleman.
3. Respect her boundaries.  
4. No means no!
5. Don't treat women as your property.  
6. Don't be jealous and domineering.  
7. Learn to communicate and make compromises.  
8. Now and then, do something nice to make her feel special.  
9. Respect her need for a social life with her friends.  
10. Don't spy on her.  Respect her privacy.  
11. Keep yourself properly groomed.  
12. Protect your lady if someone mistreats her.  
13. Be patient and helpful around the house.  Don't leave a mess.
14. Make time for her, if she really matters to you.  
15. If the relationship ends anyways, don't become some creepy stalker.  

get really hot or really rich

Try on-line first.

Turn to Jesus and if that doesn't work, we'll try with the other sex. There are a lot of men who'll find you attractive instead
