Will it last? does he really want to marry me?

I have been with my boyfriend 6yrs. things were not always good because I always felt like he was cheating. for 5 years he never came clean and I never had proof so it was always unclear. last year he told me everything and he did cheat with about 6 girls. it's been the hardest thing trying to get over with considering 3 of them were my high school friends. for a year he has not gave me reason not to trust but it's still hard to. he never calls or texts unless i do and he never wants his phone around.. and I feel the only time he is happy is when we are in his room doing the what not. once we leave that place we fight about almost everything. family and friends are telling me i deserve better but i still want to try to work things out. what can I do to make us connect a lot more and fight less? is it that he just doesn't know how to break up with me or he doesn't know how to show emotion? I really want to work things out but I want him to meet me halfway. I sometimes think he wants to live the single life and he's bored of us.
