No need to explain this one, I know exactly what you mean.Midnight Crossroads said:-If her best friend is her mother.
Things become too awkward.
For me it'd be:
Smoking. I can tolerate it but smoking generally makes me want to steer clear from a person or at least count the minutes we spend together, I think this would be counter productive towards dating someone.
Self-image issues. I don't care what anyone says but to me there is nothing more annoying than a girl who needs an ego boost every day. You know what I'm talking about, "I look awful in pictures." or "I want to hang out with my friends but they look so much better than me." Telling a person they look good is certainly expected when dating/in a relationship but when you're dating a person who shoots down compliments due to their own issues...that just sucks to no end. I've also found it quite odd to date girls who were uncomfortable with their image to the point of excessively working out. I guess I'd simply like to date a girl who was comfortable in her skin and didn't feel the need to reflect on what society viewed as "acceptable" in terms of looks.
Bad listening skills. Communication is key for a relationship. One way I easily distinguish girls I'd like to date to girls I'd only be friends with is if I could stand talking to them for longer than 5 minutes (hell a mean feat for anyone I interact with to achieve). I say bad listening skills because I have dated people in the past who can look attentive but once the rebuttal comes into play it's so clear nothing I said was grasped upon, in my opinion one of the worst things a human being can do is waste their time and I don't think you should ever have to feel as though you're doing that with a person.
