Advice ? Bare w/ me 😂

Ok, so for the longest time I’ve known I liked girls blabla etc. same story. Anyway, all the girls I’ve talked to in my life it never went anywhere passed the talking stage. I’m 18 now. There were periods of time where I struggled with concentrating on education and then my social life. So, after High school I figured since I’m in college it might be my chance to finally get into a relationship because I’ve basically done everything I’ve wanted. I have a car and I’ve had jobs, I pay my own bill, etc. Now, I finally met a girl, actually on this app around the time I graduated or even a month after. We’ve been talking and I really like her. She’s already expressed that she likes me too. It took us the longest time to actually get on the phone because idk I was just really shy. I already know she’s real cuz of the whole IG and we’ve sent live pics , but of course I never put like my wholeee face. Mainly because of insecurities. So when she ask I just change the subject or joke. She knows I’m not a catfish so I think she already knows I’m just insecure. I know I’m not cute cute but I’m not ugly ugly if u get what I mean, but she’s so pretty. Like if I actually physically saw her in person I wouldn’t talk to her straight up 😂💯. Right now she has an Android because her iPhone broke but she’s getting one soon and now I’m worried about the constant FT calls I’ll be getting from her even thoe we talk otp 😩 Idk guys I just need to hear someone else’s voice. How did u get over your insecurities etc?
