Relationships, at any stage, are a hard work and you certainly don't want to be in one with the person who is not committed to make it work and grow with you. By 'hard' I mean it's not just "happily ever after". So, all those whom you're not dating again - haven't been worth it in the first place and in effect did you a favor. It may not seem like that at the moment, but I believe it to be true.
The maths should be simple, people do on-line dating because they are openly saying they want to meet someone and are willing to put the necessary effort in. After all, the logic says the other side doesn't want to waste effort, emotions, time or money either.
But, when things repeatedly go wrong, as you describe, I think it's time for deeper analysis. Do you have someone who knows you really well, can be open with you and who can really look at things objectively for you? Because you might be too subjective about yourself and the situation at this moment in time.
The way I see it, the explanation could be as simple as "It's in the numbers; the odds of coming across the real thing increase as the sample gets bigger and you just need to keep going".
Or it could be a bit more complex, like a common denominator in all these past cases which didn't work. Perhaps you were choosing the wrong kind of men, you just need to find out what was fundamentally wrong about them. That's what it sounds like to me.
Fingers crossed for you. Deep down, I think you need to work on making ourself happy with yourself and the situation as it is, because things may or may not happen. The rest will happen if it's meant to be. All the best!
