I've been dating this girl for about 7 months now. Overall, we have good times together, and she is overall a good person. We had a really awesome and good 1st date, and then leading up to our second date, she fabricated a story that was very clearly fictional, then she brought it up during our second date and tried to start fighting with me about it. The details of the story aren't really important, and it would require a lot of typing, so just take my word for it.
Anyway, ever since then I have written her off as a potential long term partner. If I'm to be honest, the only reason I continued seeing her is because 1) the first date went so well, and 2) she is very hot and sexy, and that part of seeing her has been great. However, she's starting to hint at the fact she wants us to be more serious, and I just can't do it as I view being in a serious relationship with someone like her as a liability. If she's willing to make up random crap to fight with me for no reason, it wouldn't surprise me if she'd make up random things about me to smear me if it ever suited her too.
Am I overreacting?
