he tried to comfort me and was being sweet the next 2-3 days. The fact that he is so sweet after makes me think that this is my fault. There have been other issues like this where he may get upset about things I do like if I forget to turn the 2nd light off in the bathroom or things like that. He tells me he is willing to wait for me to learn how to do better. I feel like yes maybe it is my fault because I’m making mistakes and he gets so upset that I feel horrible for making him mad. I’m not sure if I’m wrong or he is just easy to get upset. I’m very confused and if anyone has advice I would appreciate it. He says all the time he wants to marry me and that he loves me so much and I know that he does but I want some advice on this. If you need more info let me know.
No. You are not wrong.
Your boyfriend is abusive. Full stop. This is how they operate. The turn on you then afterwards, they're all sweet, asking forgiveness, crying, etc., to get back their status quo until the next time they set themselves off. It really doesn't matter how he acts when he's being sweet--that's all part of the dance that abuser does when grooming their target. If he was mean all the time, then this wouldn't work, would it? But he lulls you into believing that it's some aberration until the next time he's shoving you into a door... then he's snatching your arm... then he's "play slapping" you... then he's for real slapping you... that's how abuse escalates. Once he no longer gets a charge out of doing what he's doing, he is going to elevate it .
The fact that he puts his hands on both you and his son in an aggressive manner should have been a huge red flag that you seemed to have missed.
And he doesn't love you---if he did, he wouldn't be putting his hands on you in aggression, he wouldn't be lecturing you on stupid mess. What he loves is having control over you.
I wouldn't marry him---he's got too many issues, from what little you've written about him, that he needs to work out with a therapist.
People treat you the way they feel about you
If you choose to remain with someone who doesn't treat you well, you cease being the victim and become the volunteer.
