My typical life

So here I am doing everything I possibly can for my boyfriend. I was working 3 part time jobs until I recently got a full time position in what I went to school for. I just don't feel like he loves me or is attracted to me anymore.. He said I love you back but that's just words.. He never compliments me anymore, he's always grumpy and tired. If anyone should be grumpy and tired its me. I help pay his bills, while paying mkne and we live in my dads basement rent free.. Sometimes I just feel like he's just with me for the free rent until he finds a job and can afford his own place.. I cry in the shower every time cause I feel worthless I love him so much, I just don't know what to do.
