This thread is very disconcerting to me. I thought I could escape it on forums dedicated to a grave and final topic, but the memes are too prevalent.
Sure you could argue personality is important, but I think we should return to reality. All relationships are built upon sexual attraction first and foremost. Regarding having deformities that impede sexual attraction, this will severely limit you.
Now here comes my bitterness, listen or don't I need to write this. They'll tell you that it's your personality. They'll tell you didn't meet their needs avoiding placing blame on unchangeable and especially stigmatized features; things that might hurt their ego or cause pity. Perhaps it's in the humans best interest to avoid potential confrontation and reflexively virtue signal, but it will cause you to believe there is something erroneously wrong with your character. It does more harm than pronouncing uncomfortable truths and confuses what the real reasons are.
Most people aren't assholes, contrary to what you might believe. Most people, like myself, are average. Average thoughts, words, ideas, capabilities; all average. This means, like an average physicality, I have an average personality. There are no types. It's if you are attractive, then comes all that quixotic crap that's supposed to make a happy relationship. This applies to both sexes and whoever you are trying to attract. It's universal, because it's nature.
Don't let me prescribe you, but you are going to struggle. Try both learning to accept yourself and accept that, because you are limited, so will your opportunities be. I'm sure you already have your ways, but I must also urge you to find copes.
I hope that you make up for that deformity with a well formed face, as that might be greater validation.
