I don’t love my husband anymore, how to force him to stop loving me?

I met someone else, who’s not worth it but to show respect to myself I’m rejecting him.
He’s the man i always wanted and pray for but he told me a year ago that he was only looking for a friends with benefits relationship. I have ignore him multiple times even though I abreast told him how I feel.
My husband 2 years ago treated me really bad but now that I want to leave him he’s acting like a b- giving me gifts money paying my bills whatever to keep me with him. We both been through rough times including his cancer but now I’m the one who has an illness and I’m done. I feel guilty because he’s acting like a kid who doesn’t want to be abandoned by his mother I can see it it in his eyes that he will suffer if I leave him and that makes me want to just leave this world but I’m only staying because I’m helping strait animals. I’m not a good perdonan but at least I tell them how I feel and he still is doing what ever it takes. I’ve done everything to make him stop loving me including stop doing household chores and told him I like other guys but my bad is that I show him who I really am and that’s why they become attached to me.
