I'm late to this thing, but is OP feeling better, 3 weeks or 1 month past?
Nothing that is good lasts forever but take solace in knowing that nothing that is bad lasts forever either.
It doesn't seem like those were such good times other than the fact you both felt you needed each other in a rough patch and didn't want to be alone. My advice that I learnt the hard way years and years ago: don't look for people that need you, specifically look for people that don't need you (independent, etc) and still choose to be with you, and then be able to think what they actually need in their lives coming from you, which is different than what they think they want, and what you think you want to give them (see, that's projection). Usually though, if you want a shortcut here, women are sick of routine, their own obligations and basically want to be entertained, do stuff (usually outside) and have fun. If you manage to strike a good balance it's on. But never compromise your mojo.
Taking the laws of the market at heart, both men and women want what's harder for them to attain. The conundrum is that we usually want someone to bring home, girls want someone to go out of home with. For us a girl to bring home is the hard part, for them a guy that does stuff with them, that actually interest them and is not routine is the hard part. Checks out.
You're clearly a giver, so don't pick people that are ok with just receiving. Either be reluctant to give so soon (or rather, if you're hurt when things don't move forward, then you're not ready to give as much; you're putting yourself in a vulnerable position after all), or, if you want to turn the book on it's head, you can do the opposite, you give early on, but if the person doesn't give back (meaning she's ok with just receiving) you move on and don't go back (in these cases they'll chase you when the giving stops, but you've seen that they basically want a satellite guy). Don't be manipulated, read actions and not intents, words, musings... Worded language is useless, what matters is what people do after they mumble their stuff.
Good luck.
And going forward, consider dating multiple women before you get all-in attached to only one.
Ahhhh, the illusion of choice.
That's one way to do it, but not the only one, you can also do it with just self esteem knowing your worth and being on top of your game, or... you can pull it out in an online messaging service, you speak/juggle with multiple *ehem* girls, even if only one of them is a target, the rest can be just friends of yours or something and you're catching up, not exactly trying to woo them or flirt. You basically want several conversations at once, so the conversation you're having with that girl you want is not centerpiece/all you care about. That way you don't come off as needy, nor are you playing ping pong guessing timings. And you catch up with friends of yours to know how's their life's so it's a win-win situation.
Anyway, illusion of choice is needed, but be aware of it's caveats as well. People with illusion of choice tend to not make decisions. Force yourself to do some decisions, always. And don't go for low hanging fruit with issues.
