Dating can be difficult and lots of people screw it up. That’s okay. Being bad at something is the first step towards being okay at something.
Remember to ask questions when you go on dates. It’s a common mistake for people to just talk about themselves. Try to ask the other person open ended questions, and engage with whatever they’re talking about. So if they say like “I went to Storm King this weekend” you can say like “Oh storm king is lovely! My favorite is the sculpture of the moving pipes that spin but never touch. What’s your favorite part?” Don’t go off on a monologue. Don’t just change the topic to something you want to talk about. It’s like a game of catch. Throw the ball back.
Also weight isn’t the most important thing. Unless you’re like so overweight it’s a medical problem, there are people out there who will be into you. If you want to lose weight (or get fit, an arguably better goal) then you should do it for yourself.
Also rejection is to be expected. Don’t let it get to you.
If you use an app like tinder, you’re going to get way more misses than hits. That’s fine. Focus on the hits and let the misses fade from memory.
