I’m in no way saying that if you’re a single parent you should just give up on finding someone. I want people who desire a partner to find one and be happy. But a lot of single parents seem to have this firmly held belief that anyone who turns them down must hate them and hate kids. No. No one is picking on you by having boundaries. Kids are a huge responsibility and a lot of us don’t wanna deal with it.
You can “I won’t put any responsibility on you”, “My baby mama/daddy isn’t dramatic like the other ones”, “I won’t neglect you” etc all you like, all of those claims almost always end up not coming true. Your new GF/BF is always gonna be a distant second to the kids – and that doesn’t make you bad. You SHOULD put your kids first. But just like you’re not bad, others aren’t bad for wanting to date another CF person and be their priority. TL;dr single parents don’t want to accept that the dating pool will likely have slimmer pickings for them. No one’s being a meanie and picking on them.
