We all have our preferences with dating. I agree is impossible to be with a single parent without being involved with their kids. I was confused when you told your colleague that it wasn’t because you dn’t want to help the man raise his kids but I guess you meant financially. I’m a single and even now I don’t see dating or marriage as glamourous as I used when I was a teenager. I’m perfectly fine living the rest of my life as a single and that’s an illusion to society.
I also know what ever we wish happens more often than not. You are not a child, so whatever you wish, be sure is a decision you won’t live to regret. I’m say this assuming you won’t ever want to have kids of yours.
I don’t bother paying attention to those who think single mums are “low standard” women. I haven’t dated anyone how saw me a such so I can’t speak much on that.
