Is It Too Much To Ask?

I just don't get it at all, I'm a nice guy trying to get a girlfriend and yet I can't get one at all. I need a girlfriend cause I want to open up to her but how can I be sure that she wouldn't tell anyone what I told her if we break up? I want a girlfriend so I could look after her and for her to look after me and be there for each other during the best and the worst of times. Some times I feel like an emotionless box cause I haven't shed a tear for many years (unless I find something really funny but you know what I mean), sure I do get sad and upset but I don't cry and I'm afraid that if I cry then a woman would dump me thinking I'm too sensitive. I'm not really sensitive at all but I do feel I need to let out my built up emotions or otherwise I would turn into an emotionless box without caring about anything any more.
