Many times singles feel obligated to find that special someone, and they would rather go out on a date, just for the satisfaction of going out. Many people simply don't want to stay at home, don't want to be alone, and at all costs, they try to avoid that feeling of loneliness. A lot of people would rather go out with someone, despite knowing that they're not the right match, despite knowing that they're not going to have a future together, and possibly the reason being that they already know that there's no chemistry between them. Either way, they don't want to be alone on the weekends, or ever really.
Don't temporarily settle
When I say that it's better to be alone, rather than settling with the wrong person (and even for one night), I hope you understand what that means. The light that I'm trying to shed here is that if you're not interested in someone, don't waste their time or yours. Going out with someone that you're not into is a truly selfish act to the other person, and to yourself. If you don't have any friends or family nearby, or any other reason that you feel is the reason for not having anyone else to go out with, you still shouldn't go out with someone if you're not interested in them romantically, or if you don't see a possible future with them.
Don't use people as a space filler
Having said all of this, true love comes when you least expect it. It doesn't happen when you're out with the wrong person. Although, I did hear of a case when it did. However, it's not a very pure, kind thing to date someone for your own selfish reasons, whether it be to accompany you, so that you won't be lonely, to date someone that you're temporarily settling for, or to date someone that's merely a space filler, etc. Definitely, and by no means do I agree with those out there that use people in any way, this includes in getting a free meal. Whether it's getting a free meal or free company at another person's expense, where a person is getting taken advantage of, it's wrong.
