I don't use her as an excuse though.
My daughter is 6, and with the limited time I get to have her, I want to spend quality time with her and not have her dumped onto someone else.
I understand where you're coming from Ms. Harmony, but I don't feel my daughter needs that conversation yet. She'll ask about people that are around, but it's just my family for the time being.

Here's a situation that I've stood by but has led to me walking away from a few of my pasts relationships. I have been told, by friends, that I shouldn't be so hard on the women I am seeing, but I'd like to know what others think about it.
My daughter is first and foremost in my life. I make sure any potential girlfriend knows this up front. My time with my daughter is primarily set at 6 hours a weekend, but her mother has been allowing me to get her more if I ask in advance. I do not let anyone I'm dating to meet my daughter, and I feel I have a valid reason for this. I don't need my daughter getting to know someone one day if they may not be around for very long. The women that are around me when I have my daughter are just friends.
On multiple occasions, I've had girlfriends complain that I don't make an effort to see them but it's because I have my daughter and have plans with her. I feel I'm not wrong in breaking up with them for trying to put themselves ahead of my daughter. However, I've had a few friends tell me to ease off and let it go. Personally, I don't think people should put themselves between a parent and their child unless it's for the safety of the child.
