Do you meet many men in your day-to-day life, ie job and free time?
If you don't, then it's highly unlikely that you will get into a relationship? Sure, we've all heard of people who met their partner in the queue to pay at Sainsbury, but those are the exception rather than the rule. It's not easy to change job, so whatever you do when you're not working needs to include more single blokes. Classes or hobbies aimed at them as well as women, bars they go to, online dating (counts as meeting men) etc. If you aren't meeting men, a relationship probably won't fall into your lap.
When you are meeting them, ask them out. Ignore the often posted bollocks about men don't like to be asked - they'd prefer to do the chasing. Some will, some won't, but few will reject the advanced of a woman based on that.
And, of course, try not to come across as desperate as you're coming across on here. You want men to think you have fun in your life, and thus it would be fun to date you. If you are having a hard time at the moment, then I'm sorry to hear that, but that isn't going to attract a potential date.
Do your female friends know that you feel like this? They might have some single male friends to whom they can introduce you.
