@namechanged9999 and @Shayelle2009 the whole waiting for someone to reply is torture! But one thing I've decided is that if I want to message someone I will, even it breaks the so-called rules. If the last conversation ended with mutual smiley faces, then he may be sat there wondering why you haven't got in touch with him. Or he may have lost interest, or is simply busy - you'll never know, and it's pointless trying to second-guess what he's thinking. Just be you.
If he likes you, he'll be happy to hear from you. If he isn't that into you, then whether you do or don't send a message isn't going to change that.
As for replying instantly - I'd say mix it up a little. Sometimes it's nice to have conversations where you reply instantly, but other times it's nice to just check in with the other person every few hours. Don't play games, but do stuff to make yourself genuinely busy so you're not sat there with a stopwatch ready to reply as soon as x minutes are up.
Also if someone questioned me why I hadn't replied in 6 hours I'd be a little miffed as 6 hours isn't long at all really, and that comes across as a bit needy IMO. If I'm out with friends, or busy with work then I may not check my phone for hours. Also constantly checking whether someone is online on WhatsApp, or looking at your phone for a reply is quite simply torturing yourself. I have to force myself to avoid that by leaving my phone at home and going out for a bit, or turning it off and leaving it across the other side of the room so I'm not tempted to constantly check. I've done the WhatsApp status check with a couple of ex-irons, and it almost drove me insane - it's really unhealthy.
I've decided to take the extreme step of deleting my Bumble and Hinge accounts, and I'm now down to just Tinder with one match. I've been off Bumble for a week now, and will probably re-create myself tomorrow or next week. It was a bit sad deleting Hinge, as I had a number of chats archived, including my first messages to Miss H - but that's all in the past, and it's time to have a fresh start.
As for my terrarium course, it was really good! There were around 20 people there, with a mix of couples and groups. I wasn't expecting to meet anyone, but it was just lovely to get out and do something fun with random people. I've attached a pic of the terrarium I made
