What's wrong with liking good looking people? Yes there will always be someone too shallow. But to be honest, I find guys more guilty of that than girls. At least in my experience I see more girls liking a guy for his personality than the other way around.
And, why is this even a concern to you? If she is shallow you don't want to be with her anyway. Problem solved.
You're falling into this trap of a self-fulfilling prophecy. The more you think like that and base your behavior on those thoughts, the worse the situation is going to get. The truth is there's only a small amount of girls out there who only want guys with model looks. If you're ugly (and not just perceiving yourself that way because of low self-esteem) you might have a harder time of it than other guys, but it's far from hopeless.
Different women have different expectations. So stay confident, but don't be a douche. The right girl will like you, but if you think you are less than average looking, don't go for average or above average women. Sorry, sad truth
Well about 50% of people with partners die alone anyway if their partner dies first, so its something a lot of people have to contend with.
As for not being able to get a partner its going to be far harder if you are ugly, especially with attractive girls who are almost completely unobtainable for ugly guys. The obvious answer is to go for less attractive women, it still won't be easy though, just hang in their and keep trying.
The other alternative is to work on making yourself less ugly. Depending on what issues you have the advice would be very different but no matter what is wrong with you its possible to make significant improvements. Try the obvious stuff like working out, buying new clothes and experimenting with a different hairstyle. If that fails look into plastic surgery and/or steroids.
I've seen my fair share of cute girls with ugly dudes. My girlfriend used to date this homely looking grocery bagger before she dated me. And my girlfriend is the highly desired type.
Plus ugly girl's have hope too. My poor cousin was a hideous little girl who had to get a serious nose job to look remotely decent (enormous nostrils we are talking about). She eventually got married before 30 and eventually landed a supervisory job and a big corporation.
If you think you're ugly, go for the ugly girls then. I bet you're not doing that LOL.
How many guys have model/actor looks? 5% maybe, at most. You do the math.
