Procedure for getting a new girl after a breakup

Considered posting this in the Relationships area, but it's still a newbie question.

Let's just say I haven't had a lot of girlfriends. I'm not going to complain about that this time. I've been doing a lot of things wrong. At least I now know what they were. I'm feeling good about my ability to attract overall. The point is that I certainly haven't had girlfriends serially - with small gaps between them, as many seem to.

In these questions I'm not talking about one night stands of fuckbuddies, I'm talking about relationships that last weeks and months...
Some guys have to put up with celibacy / no romance, for months. I don't think any guys like being single, whereas girls seem to like it, or at least they are good at pretending to like it - freedom etc. A guy's wife of many years dies, and I've seen it: he is seeing or even married to a woman 10 years younger than his late wife within 6 months. Some guys can't stand a gap. Who here feels like they want very short gap? You might want more gap if the last relationship was emotional. But what does an alpha or a pua do when a relationship ends, assuming it didn't end because he was already seeing another girl? Do you literally just decide that you need constant access to a woman's body, any woman's body and you just go out every night and day until you find one and then you can relax again, even if it takes a month?

Is that what you're supposed to do? Loads of sudden concentrated effort. Are some of you driven to be single for only a short time. I've never done that. But my gaps were expected to be big, so I've never got used to being in a relationship, so I don't notice the absence as much as some. I didn't have a lot of girlfriends because I just assumed they would sort of turn up or approach me themselves. Some guys just seem to fall into relationships. It's not just that they APPEAR effortless. I suspect they are REALLY making no effort, but they're having everyday incidental contact with women in their lives anyway and they're attractive, easy, handsome, well-groomed, by default and so no CONSCIOUS effort is needed.

I'm tortured by the concept that "It is easy to get a girlfriend!" because it is both true and false. If you really want one, it isn't. If you don't, but have a busy social life, it is. Correct? It's easy or hard (or impossible) depending on your game, your expectations, your desperation and your lifestyle?

How long a gap could you stand? And how do you go about making sure a gap is short, if that is your preference? Approach every girl? Be impatient for a girl without seeming to be?

If I need to make efforts like that, I need more motivation and less nervousness - more exercise, and no salt, caffeine or masturbation.
