The poll results are interesting, it seems some people see relationships as too much hard work. Its true there are expectations but on both sides. There was a blog on CS it said his wife left with his neighbour that she was a good mother, looked after the home but didn't give him love. I replied, there is a saying "I want a wife and not mother" a mother gives care and loyalty and a wife wants to feel attractive, special and part of the mans life. The guy became offensive because too many men feel a woman is just there to cook etc. like that's the womans duty and that she's no more a person in her own right, that's where marriages fail through lack of respect. You could argue that a woman could do her bit to spice up the marriage to stop the guy straying but I think it's just in the nature of some men to stray from the marriage.
No you're not ready as many have stated here. You need to examine why you're lonely and depressed and work towards improving your situation by getting new interests e.g. exercising or photography and aim at your life in order.
I think men are taught they need to do the running and when a woman runs after a man it is often looked upon as desperate or needy. I'm sure that by doing small thoughtful things for this man he would begin to notice and think about you as a caring person. Obviously if its been stated he is not attracted, your the wrong age etc etc you can't hold a gun at his head an make him declare love for you. (well you could but it wouldn't be a nice way to go about things)
Do you feel safe meeting someone from the internet?
You're a true gent.
