You're swiping through Bumble. You see a handsome and well-spoken gentleman. You swipe right. You match!! You message him (on Bumble, the woman has to write first)... only to get no response. The 24-hour period where responses are allowed is up, and -- poof -- your match goes away just as quickly as he got there.
The question is this: If someone looked at your picture, presumably liked what he saw, and then swiped right, isn't he interested enough to write something back? Let's look at six reasons why he may not reply to you, in order of most likely to least.
1. He swiped right without reading your profile or looking at all of your pictures, but when he did, he was no longer interested.
Sadly, this is probably the most likely scenario. He saw your first picture. You're really attractive! You match -- yay! You write to him, assuming he liked what he saw. Then, when he gets your message, he reads your profile and/or looks at the other pictures and decides, for one reason or another, that he's just not that into you. Women often use all of the information they're given (profile, pictures, etc.) up front and only swipe right on those they want to talk to. Men, generally, use much less discretion. As in, they make decisions based on one photo and nothing more.
2. He's not that attracted to you (sorry) and swiped right on everyone.
It's true -- some men, knowing how discerning most women are, simply swipe right on everyone to see every single person who likes them in return. So, they may not be interested in 1) dating at all, 2) everyone they swiped on, or 3) even looking at the matches once they come through. This could just be a game or ego boost to them.
3. He forgot.
Sometimes people look at their matches, say they're going to write later, and then simply forget. If someone likes you enough, though, he'll remember to write back... or pay to extend the match. (Once a woman writes in her 24-hour period, the man has 24 hours to reply. If one of these conditions is not met, the match goes away.)
4. He's busy.
He has to call his mom for her birthday! He went to the dentist to have a root canal. That report for work is a week overdue! Sometimes people are just busy and don't make dating a priority.
