Affiliate Marketing Secrets

I am 25, I have a full time job, but I am not very career-minded and all I really desire is creating a family life, finding a nice girl and settling down that way. I don’t seem to be able to meet anyone, and when I do chat to girls at work, I cannot seem to break past that ‘just a colleague’-speak.
I am from the UK, but I have tried a few different methods of trying to meet people. The problem is that I partake in things that I am not really interested in, simply to meet people, and therefore it never really works out. I always come alway feeling rubbish that I haven’t met anyone, of at least been able to connect with someone other than saying Hi, bye” and smiling.
I have tried numerous different ways of meeting people, but because I am not a big mixer, I find it difficult for anyone to really take notice of me. I am one of those quiet, but über polite people who always smiles and makes an effort when spoken to. I have tried evening courses, but people are there to learn and not meet people so I come away feeling dejected and end up dropping out of the course, losing money in the process. Language classes also give off the same impression. I have been on meetup.com, but that hasn’t taken off in the same way as it may have in America. The only meet ups on there are either in London or niche community groups that are a little too ‘nerdish’ like Dungeons and Dragons clubs and board game clubs – both of which I have no active interest in myself. I don’t really have any specific passions in honesty. There are no causes that I feel strongly towards, so I am not sure what else to try with the only voluntary work I would be interested in would be dog-walking because I love dogs. Again, it is not exactly an avenue you would meet anyone in. I have to be interested in so,etching to engage with it, otherwise I will just get depressed and frustrated doing it. I wouldn’t be able to stick at things such as fundraising, etc.
I don’t have any real friends so meeting somebody through a connected social circle also isn’t an option. I do have one person from work who makes time for me, but that is generally only to go to the cinema – and there is no chance of meeting anyone new in a darkened room. These cinema events are only very occasionally as well, say once every four or five months.
I have been on online dating websites for more than six years, but I have had no luck on there either. I have never really received messages from anyone interested in me, the messages I send are on the whole, unreplied to, despite trying to make as much effort as possible. I have had my profile reviewed by several people who give me the thumbs up after suggesting edits and I put up clear pictures. Sadly I don’t think I am attractive enough for online dating so I have kind of given up with that particular medium as it has just exhausted me, and has led to bouts of depression and feelings of worthlessness.
My hobbies are quite solitary I guess. I like listening to music, watching films, really into foreign cinema espeically korean flicks, browsing the Internet, playing some video games. I don’t really like sports, but I do exercise at home so I am not overweight but I am quite a slim person in comparison to the average guy.
Any help? Help that avoids the suggesting anything that relates to religious salvation and the worship of human-crafted false deities and men in the sky if you please? =]
Thanks
