dont I think the point that people are trying to make is, that you haven't ever properly been single to be able to say how you feel about it. You've either been in a relationship, healing from one or pursuing the next one. You've never stood still and just been yourself. You've always seen yourself as one half of something. And if you keep saying ''I won't ever be happy single'', then, well, that's easily a self-fulfilling prophecy.
I learned a word here on MN recently - limerence - google it and read some of the articles on it. It gave me some perspective on why to so many people outside of a relationship, it is ridiculous to say that you love someone after such a short time. I dated that guy I 'found' when last on the dating thread for 8 months this year, spent almost every weekend together, and usually 1-2 weeknights as well, went on holiday twice, met each others friends and family. After all that, it turned out I still didn't really know him at all. It takes a long time to properly get to know someone. And you can't love someone that you don't know. Those quickly developed, super intense feelings, are not real love.
Having followed the first of your 3-month relationships (I'm assuming here) via the dating thread, my word lovely you DEFINITELY dodged a bullet there. That very very quickly became horrendously unhealthy for you. I remember actually being worried about you, and I'm just some random stranger on the internet. If the next relationship followed the same pattern, then yes, taking some time out would be a really really good thing for you.
For me a great antidote is reading the relationship boards here. Or anywhere else where you repeatedly see people posting about their horrendously disrespectful, nasty partners. And thinking carefully, how you don't want to end up like that. (And try to post to help/support these people too....rather than just use it as misery porn!)
