I would never date someone with a kid and I'm 23. I had a girl bring what could have been her daughter to a date. She claimed it was her sister. I stuck around for the entire date but after that, we just stopped talking. The date was awkward. The kid made things awkward and it will make things awkward no matter what.
Be nice about it. I wouldn't pursue a relationship with someone that has a kid because it's too much emotional baggage. Everyone has baggage, but when someone is seperated with a kid, it will make things complicated for you. However, if you can look past the kid, then go for it. If not, then leave (in a nice way).
I will do my best to reply with an educated, humble and honest answer. Ultimately, it is up to you whether you want to listen to my advice or ignore it completely. Sometimes, my advice may be wrong; occasionally, it will be right. Regardless, I want to do my best to give people answers they are seeking.
