How can I prevent myself from getting too invested in one girl? This isn't a case of me being an inexperienced guy that constantly gets attached to girls after one date. I'm extremely picky and unimpressed by 99% of the girls that I meet. I know you guys like to preach abundance mentality but that's a really difficult mindset to have when I only meet a few girls a year that I consider to be girlfriend material. In the last 12 months I can only think of 3 girls that I met that I was truly interested in. I just recently found another and I'm starting to fall hard for her and I'm terrified that I'm going to screw it up by getting overly invested.

(disclaimer: I'm no longer particularly interested in hook ups I want an actual relationship)
