Let me tell you a story here. In my mid 20's I met this AMAZING girl. She was super hot and had a great personality...was into geek culture and comics, etc. She seemed to be the perfect girl for me. I ask her out and she says yes. We have lunch a few times and have these super amazing phone conversations. The kind where you really connect as people and feel something happening.
Like you she was on my mind ALL the time. So, she worked at a jewelry store and I needed to buy my mom a birthday present so stopped by her store and bought a nice necklace for my mom. We're talking, being flirty, etc. She asks me to hit up a bar with her that night and drink with her and her friends.
I get there and her friends are really cool. One guy keeps buying me shots and we play some pool. Things are looking REALLY good, right?
Well, I'm talking to one of her girlfriends and this guy walks in...kisses her on the mouth for a LONG time. I'm thinking, "What the hell is going on here?" Her friend sees the look on my face and says, "Oh, I thought you knew...that's her boyfriend".
At no point in the month of talking her up did she mention a boyfriend or ANY other guy. So, I'm at this strange bar with a bunch of her friends and watch her snuggle and make out with this dude who looked like a child rapist.
Thankfully one of my best friends was in the area and came to the bar. He brought his brothers with him and we just got super drunk.
I called the girl the next day and asked what was up with the boyfriend thing. She tells me, "Well, I just thought you wanted to be friends". At NO POINT did I just want to be friends! I was VERY specific about my intentions. Mentioning things like, "I really wish I was in person with you so that I could give you a kiss". So, I basically told this girl to go screw herself and that leading other guys on isn't something she should do.
Never saw her or heard from her again and thank goodness. Shortly after that I hit a great streak of women...had some fun...then met a great girl, who unfortunately I broke up with a few months ago. However, that's how the cookie crumbles. So, when things are at their darkest...there is always a bit of light at the end of the tunnel.
And, yes, there are going to be women out there who will be crazy and play some really messed up games with you. So, trust me...I know how you feel. However, plenty of fish in the sea.
