There is this girl I know for a long time now.. We like each other a lot. We dont really have the same friends and are not really similar to each other. Anyway there is a specific chemistry between us even we only see each other pretty rarely as Im studying abroad. A year ago we went clubbing had fun and made out. it was great. However, I just got back home for a couple months, thus I texted her, and we met two days ago. Everything went well until I suddenly got super tired. I'm usually quite good with girls, especially when it comes to flirting, keeping conversations etc. but this time, I was just too tired and kinda fucked up the energy by not being exciting etc. We still had a chilled time but there was no chance of getting more flirty / intimate. Now seddit, how should I approach her again before I leave?
