HELP how do I get him not to make me feel bad about ending it!?

My boyfriend cheated on me 5 months ago and told me 2 months ago. I knew he cheated but he always denied it. And then one night he came clean BECAUSE I FORCED IT OUT OF HIM. He has been lying to me about wanting a family. He lies to me all the time. He can’t tell me his true feelings. He only cares about his video games. He RARELY helps out around the house.

I have given him 5 chances to be a better person because our relationship is super toxic at this point (I have really bad mental health issues) and he has failed me. I tried breaking up with him multiple times. Recent was Saturday. Here’s our text (I did it in person before the text and he said think about a break and I was considering but I came to the conclusion I don’t want to be with him anymore even though I still love him)

I told him I want a week break. But I want to break up with him. He makes me feel so bad when I break up with him. (I don’t feel bad breaking up. I feel bad because what he says)

LADIES HOW DO I BREAK IT OFF WITH SOMEONE WHO DOES THIS?
