I’m breaking up with potty training

I have a 3.5 year old boy who’s been potty training for over 6 months (feels like an eternity though). Most of the time he pees in the toilet just fine. At night, he NEVER has accidents. I waited till he was showing EVERY sign that he was ready. I tried every method. The no more pull ups, naked, making him clean his underwear, bribes, sticker charts, rewards, and more encouragement than I knew I was capable of. He just can’t figure out the pooping part. Actually I take it back, he’s figured it out just wants nothing to do with. He’s pooped in the toilet on a few different occasions but still lacks interest in it. So today with my heart filled with guilt and failure, I put him back in pull ups and decided that is that. I feel ashamed that I couldn’t get him potty trained. I feel shame when people ask me why he’s not in preschool and I tell them that he’s not potty trained and can’t go. I feel guilty for failing him and not being helpful enough for him. I know that potty training is not for the weak, and maybe I’m just weak. But I’m here to say that the guilt and the shame are not enough to keep me around this time. I’m done. I’ve also got a 2 year old to think of and I’m pregnant with baby 3 (and I’m high risk) so I just don’t need the added stress. And frankly I don’t think he needs it either.

My question is has anyone given up and then had success with your stubborn kids? Is it just a matter of letting him be in control of the situation or what? What’s it gonna take to get this kid out of pull ups?
