I did not read through your history, but I saw the post with your picture. I know that 'feeling ugly' often comes from inside and low self-esteem. I do feel like that sometimes as well, even though I know I am physically not ugly. Given how this mechanism works, you might not believe what I say, but at least consider it from a random internet stranger: you are good looking. Seriously: cute, handsome, sweet. Objectively speaking you are damn attractive, and I don't feel that about dudes often. Now personally people will have different reasons to not want to date you: one of them might be simply because they are looking for somebody else: they have figured out what they want and you are not a match. Another might be that they are not attracted to you, because they are attracted to other types of people. Either case should have no impact on your self esteem: you need to learn to get it from within yourself, rather than from women. If women sense that you are seeking them to improve your self esteem, they will run for miles. (I know, because I am a woman).

You are attractive man, take it as granted and confirmed and act based on that: if somebody does not want to be with you, it is not because of you, but because of them: they have different priorities, different tastes in people, different things which make them 'tick' with the opposite gender. See it as such, and move on.

You need to first develop a positive relationship with yourself: enjoy being in your own company, be self-sufficient, basically be capable of surviving, thriving and being happy without a girlfriend.

If you achieve this, I guarantee you, you will radiate so much charisma that you will not know what to do with its effects :)

Figure out what you want in a partner and what you don't want: if you have a low threshold of what you want, you risk putting your attention towards people who have zero capacity to make you happy, who realise this, and reject you, and contribute to your low-self esteem.
