You’ve 3 issues
first neighbours. Don’t buy the “we’re disappointed “ as that is just shaming you and does nothing but make them feel superior and belittle you. That’s all about power and control. Black rock that and do not respond to any accusations or comments like that. Don’t feed it as a line of conversation by expanding, agreeing or denying. Just ignore like you haven’t heard it, Instead just tell the simple truth. I apologies. I do not really understand why I didn’t stop and tell you (don’t expand on thst, don’t answer any question in rpsonsel state it. Don’t budge.) explain I didn’t feel a bump, so I was sure there wasn’t damage , then state but that no excuse is it? I apologise and it’s a wake up call thst I need to slow down a bit and just stop next time something like this happens and sort it out then and there. Check and ask if they’ve thoroughly checked their car over. Apologies again. . Leave immediately
secondly husband. Ask him to hear you out without interuption. . Tell him he is not your keeper, you will not accept him shaming and belittling you . Everyone makes mistakes, next time he grows a baby form scratch and is still recovering post partum form birthing, and exhausted with lack of sleep he can then have a more rounded view of what is acceptable and normal or not. But for now he needs to back off, accept you are human, flawed, exhausted, going through bodily changes still, and will, absolutely , continue to fuck up certain things. Just like he’s fucked up by talking to you in such a patronising way, undermining your confidence, and generally piling on misery. remind him to pull the plank out of his own eye before he removes the speck form yours and find a little humility. then Walk away.
and lastly, forgive yourself. You’re human, we all fuck up. You’ll have loads more fuck ups in your life. Accept responsibility and apologise and repair the damage done . Then have compassion to yourself. If you had a friend tell you she’d done this, you’d be offering a bit of tea and sympathy, and then probably, eventually, having a laugh togther about how utterly dumb she’d been in not saying anything, and what on earth came over her!
ps, if DH continues with his shaming you act..seriously, you need to think about your relationship and see if he’s up for marriage guidance to nip in bud before it escalates to open abuse.
