I feel like sticking up for OP, she's getting blasted because she has certain values and beliefs that don't conform with other people's beliefs, experiences, past or present behaviours. Like she's been transported from the 1950's or something.
The poor woman has been through a hell of a time, due to her child she's going to have to associate in some form with said abusive prick, most of her child's life. Which is a trauma on top of everything she's already endured.
Ok not everyone is advocating you bring home a new man every month during your child's formative years. Here's an opinion of mine, I've never had a one night stand, I just just don't get the whole concept. That's whilst being of legal age when Cosmo and other mags focussed solely on how to pleasure a man and give him the best sex ever, or best blow job ever. I can't see what you'd gain from such a short liaison. That is solely my take on it. I know women act in different ways, that's their choice, this is mine. Especially after a night out it's hardly going to be a mindblowing orgasm fest. Each to their own.
Their are exceptions to the rule, I've known people date pregnant women and take on the responsibility of being a parent, to a child that isn't there's, kudos to such guys. I can't imagine how it would impact them emotionally. I had a short stint of watching JK, where Dads believed themselves to be Fathers but weren't, but swore to be the Father figurehead in that child's life.
Another point that could be discussed is, at what point does a person you're dating, for sure, be viable as a long term partner.
I saw one example, couple meet, woman has child, guy is overly obsessed with child. Child grows up with a Daddy, plus another guy they call Daddy. I can promise you that shit is confusing for kids, as a friend commented how their kid had a friend in care, so semantics are discussed, the relationship with the other guy didn't last even though they got married. The child asked their Mum before bed once, which of the men was their real Dad, the guy they called Dad who was their real Dad, or this other guy who was in the child's life a few years. How long the child had been harbouring those thoughts is anyone's guess. That initial situation, meant the Mother was protective of who was involved in her child's life, ever since I don't think she's ever introduced a guy to her child.
It's situations like I've shared, two completely different scenarios, plus the impact on the children. But no one seems to be fussed.
I do wonder about dating sites, if you advertise yourself as a single Mum are you opening yourself up to weirdo's? If you don't mention it, are you deceiving the other person, or potential life partners of both sexes? It's a pretty big thing to most people.
You also hear stories about how Guy dates single Mum, is introduced into the child's life, couple split up, the guy is left heartbroken as he's had a bond with said child. Seen milestones etc. I know of one guy who would never date single Mums because of the way it impacted his friend.
I think it's a valid query, the views are the OP's, people aren't in agreement, but few are taking into consideration her past relationship experience. I find that really sad, as those that see freedom of dating post partum as feministic, but don't subscribe to supporting women who have been through trauma. Adding to their existing mental health trauma by some pretty harsh remarks. If we bear in mind we should accept others view points, is the sisterhood a myth?
