We all have them....people we may have hooked up with, or had some spicy text conversations with, that we probably enjoyed....but what do you do with those people when you start seriously dating someone? You may think you are doing the right thing by "telling them you are dating someone" and Yall are gonna be "friends". Yeah ok....so if this person brings up sex everytime Yall talk, they ain't ya friend. They will be gone the very minute they find someone. They also don't respect that you are trying to build something special with someone. The right thing would be to shut the behavior down.
Here is the risk. If you allow the behavior to continue, you are telling this person it is ok, that they actually may still have a chance with you, but most importantly you run the risk of the person you have grown to care about seeing these messages. Why run the risk of losing something so great over something that really wasn't there to begin with. Wouldn't it be great if that person found the messages where you are shutting it down? Just think about it. Don't let citizens of Thotland ruin what could be the best thing that ever happened to you. Dating is scary, Yall. Especially when you care about the other person deeply. Now the commitment to each other can't be rushed, but you MUST be respectful and consider each other's feelings when it comes to members of your past be it virtually or simply crossing paths walking down the street.
