Fiance's sex addiction ruining out sex life??

Hello..so my fiancé of 5 years and I have a 3 year old daughter and a boy due on Halloween. We get along great except he has real money issues like he can't grasp the we are a family and his money is our money. He can be verbally abusive but the things he says he claims are in anger and he dosent mean. Even though it's always the same comments and daily. He dosent want to be with me and hates his life to how he can't wait to get married. He confuses he daily and sexually he makes me not as attracted to him when all the mean comments are still fresh. I have always had a high sex drive but having 4 kids (3 from previous marriage) it can put a damper on spontaneous sex! Since we met he has always been a porn addict and loves the casual encounters on Craigslist. Has never bothered me as he and I have always been open about these things and also he mainly looks for fun! His porn watching and other things have never bothered me because it has never affected our sex life he always seems to want me over beating off. Lately though i've noticed he seems to be sneaking away when I'm not available to do it and doesn't even try with me. Also sometimes it seems like that's all he cares about physically with me never cuddling or just hugging or kissing me it's always right to messing around. I don't mind that but love is such a turn on in itself. He also accuses me of never putting out even though we do it pretty much daily. He makes it feel like a chore and it's not even like that to me. I want to know if you guys think if he cut down some of his constant sexual consumption internet wise do you think it would help our sex life i.e. cutting the porn down and I've noticed on Craigslist he only tlooks at women for men and he used to look at couples forcouples kind of things
