I have been single for 16 months. Sometimes I feel like this. But lately I've realised that any bad feeling I get is more due to other events in my life and not for being single. In my opinion, it's a lot easier being single when you've never been in a relationship than when you have done. I don't get as infatuated as I used to but when I do I remind myself how much of that is projection and as good a guy as they seem to be, my impression of them is not based on full knowledge about them.
I'm glad I've been single for long enough to do the hard self-analysis but I know I could conceivably be single for longer. I do sometimes long for a relationship but at the same time, I want to make sure I get the most out of life and opportunities which I may have missed when I was tied to someone else. Whether you like it or not, there is always something you miss out on when you're in a relationship, especially when you're young. There are some character-building experiences I haven't had yet. Before I became single last year, I had been in relationships since I was 17 so I never learnt self-sufficiency as much as I needed to.
It is easy for me to meet guys and good ones at that, but difficult to find guys I bond with on a deeper level. I've revised my standards so I don't have ridiculous ones but my standards are very high on aspects of character, morals and temperament which is really important to me. Although I'm only 23, I made a decision to waste as little time as possible. It doesn't mean I'm going on an insane husband search. I just don't see the point in getting involved with someone if there's a voice in my head saying "are you sure this feels right?". I don't want to use someone as space-filler nor have someone do the same with me. I've been in enough relationships to know what I want and what I don't. I wouldn't date a guy unless I thought he had the potential to be a good husband. Otherwise, it would do me too much pain (I'm a sensitive person). I want to date guys older than me - and they have plenty of options so it's harder to find a relationship than it was when I was 18. This is partly because of better self-knowledge and revised standards as well.
And I agree with what someone put above. If dating ever gets too frustrating or you're feeling too desperate, you must force yourself to take a break.
