IMO...the worst thing a woman can do in the early stages of dating is talking too much too soon...like divulging drama/gossip about friends or co-workers ect...it can make you look catty and messy bc I don't think men really care about those kinds of things in a relationship let alone someone you're just getting to know...
From my own personal past experiences, complaining all the time about stuff can cost you points too...went on a date with a guy once and bc I was nervous and couldn't think of much to say I kind of went on a tangent about customers at my job...he would laugh at some of the things I said but we ended not talking pretty soon after that night and I later heard from one of his friends that he liked me initially but bc of all the complaining I did he thought I was a miserable person lol tough lesson but I learned from it...even though Im in a relationship now I watch what, and how I say things to new people bc honestly it's annoying to talk to people who always have something to gripe about and that goes for men and women alike.
On the other hand I also believe that letting your home girls know too much about a new guy can ruin things too, especially if they're your best friends. As women we want the best for our friends and if you mention too much about a new boo to soon they could judge him knowing only half the story (what you tell them as opposed to what they actually see him doing/saying). Or they might think he's ugly, or a player, and warp your opinion on a guy that could be a good match for you. Now that I'm a little older and wiser I like to keep things close about me and who I'm dating until I've gotten to know a guy well for myself before getting my girlfriends involved, that way something petty like looks, who his friends are, who he's dated in the past, etc, won't distract me from giving him a chance. My friends can be mean and extra picky about guys and if you aren't careful their quick judgement can effect how you feel about someone new...
