Whats a good r&b song to dedicate to my bofriend in this situation?

I want him to know tht I really do love him and tht he cant countinue to tlk to his ex or im gone-and he never wants me to leave him,and he says hes gonna wrk on it.He said hell be miserable if I left,we also have a kid together.Any songs I can dedicate to him,to let him kno tht I care and want to hold on,but not if he continues to hurt me.
