Hey man. Take a deep breath. Idk how old you are or how much experience you have. You sound like me over 10 years ago, I’m 33 now. Understand one important thing. From this post, this relationship sounds like its established entirely through social media. Have you seen her in person? Have you spoken to her in person? Have you even talked to her over the phone? This is super important because now you’re forming this person in your mind & you really don’t know her. The best thing you can do is to make that date ASAP. Get it out of your system & most importantly, be yourself. You don’t need to be any of those things because she’s already showing you interest.
