My heart hurts..

so me and my boyfriend have been together almost 3 years... he's black .. I'm white.. recently he is just distant.. we have been thru a lot in these almost 3 years.. he cheated..I miscarried... just a lot of stuff... we are trying to work thru it all after a 6 month break but I feel like it's all starting again... he is starting to act the same way he did before when he wasn't faithful... when I say I love this man to the ends of the Earth that is true.. I have never loved someone like I love him... things just don't feel right ... he's also showing a lot of interest in black women.. l just feel like I am not good enough anymore... all I do is cry... we have zero communication... he doesn't seem to care how I feel or want to hear it at all.. he's a student I work 7 days a week to take care of us.. and on top of it he has a terminal child... just don't know what to do anymore... I'm so tired of being sad and unhappy...
