1) on valentines, all my friends with couples go out with each other. Sucks that when your friends get a gf or bf, they suddenly only want to go out with other couples. They seldomly invite singles unless it's a best friend.
2) Valentines to me is just as important as Christmas and others: not important at all. Now there will likely be an uptick of women who want to get a man on valentines, but it's more of a fantasy than reality I imagine. I never saw much change in the social standards during valentines day. And most women would likely find someone on social media or a dating app before going out so they wont suffer the embarrassment of being alone on that day. Alternatively, women will group up even more to protect each other from the fact that they have no one to go out with. So if any guy is thinking puss will be easy during this day, they got it wrong.
3) There are ways to make good out of this day but you have to be creative and still have game regardless. Valentine's is no different from any other day. An expert would probably find this day easier than any normal day cause women's emotions are heightened, even if they are out with a bf.
