on some real shyt breh stop that shyt. you're stressing yourself over p*ssy and that's the vibe you'll give off while talking to her if you don't relax. you're acting like it's 20 minutes before a big performance or before a big job interview. snap out of it. remember how you felt when you chatted with her online. you cared a little but it wasn't a super big deal. that's the dude she fell in like with. remain that dude and you're good. start morphing into a nervous wreck and you won't feel happy during the convo.
fukk if she likes you or not. she's just some girl looking for a boyfriend/attention on a dating site. my homie, she may very well be a loser! and you're worried about making a good impression on her???
she should be the one worried about making a good impression on you! she already started choosing you. it's up to her now to prove she is worthy of being chosen. don't let her trick you
you think she doesn't feel that way eventhough she'll try to hide it? TRUST ME breh, 98.6% of them are LOSERS looking for some dude to give them direction and purpose. don't let the make-up, clothes, perfume and jewelery fool you. don't let her "sweetness" fool you.
*disclaimer: not all women are what i described. but a lot of them are. and if you met her on a dating site you increase the odds.
