Is it normal for my boyfriend of 5 years, to hate kissing me in the lips?

My bf is going through retro active jealousy, and now he doesn’t want to kiss my on the mouth. I feel like he hates it when I tell him something sweet. For example I’ll look at him and think to myself, “damn I love him” and I hesitate to tell him I love him because he’ll say something stupid like “ but I thought you liked your ex(so and so)..” and it’ll be little me because I feel like I’m in love with someone who doesn’t love me back the way I deserve to be loved. He’s my 5th everything, and that bothers him to the fullest.

So is it normal to be dealing with this simply for our son? Is it normal that he hates when I say something nice to him, because he feels like I’ve said it to everyone else, but he doesn’t understand that after 6 years of being dedicated to Only him, giving up my life and friends, to have his Son and live with him and build my world with him, something I’ve never had with anyone else!!! I feel like He’s doing this to me because I made him feel guilty about google searching a pornstar, and looking at her google images WHILE at work. Ever since that he’s been using my past against me and says he hates me and wishes I was dead and wishes we never got back together the first time we ever broke up. But I get confused because I never knew he felt that way because he always loved me and never acted like he wished we were over after we got back toghether from our first break up. It’s like he says really hurtful things to me just to get a rise out of me and hurt me where it hurts the most. He’s even thrown things at me, like my iPhone, he gashed me in between my eyebrows and my scar makes him mad because now I don’t look like how I did when I didn’t have the scar. He bruises me arms from when he pushes me off when I try hugging him when he’s talking about my past and “slut shamming” me. I guess that’s my fault for not giving him his space when he starts his ocd thoughts. I’m just done with feeling numb and trying to act like it doesn’t bother me just so I don’t know him it hurts me. But I can’t help but cry because I feel stuck and I feel guilty for even wanting to deal with this.
We can be fine all week long, and then on the weekend, he’ll bring up my past any way he can think of and then start thinking negative about me and start fighting all day long. Then if I try hard enough, by the next day we’re fine again and he’ll act super sweet and take me out or buy me stuff and spend time with me and act so great where I feel like things are ok again. Then randomly!!! Will start bringing up the past and things I’ve said to him because I trusted him, and using it against me. And I wonder why he does that, when I’m loyal to him and I’m at home all day long taking care of our 5 yr old. I’m $dependent on him because he makes good money and always tells me to not worry about working that he’ll take care of the income. But it feel the opposite when he brings up my past again and degraded me and it’s like why tell me something and then the next moment you say something else. God man I feel like I’m due for a heart attack or something really soon because I get a weird chest pain.
