Help, he ignores me on weekends?

i see my man a few days during the week mostly now its just for sex he says he loves me but when his cousin comes around for the weekend he ignores me, or either calls me all drunk on the weekends.we've been together for about a year, the sex is awesome but I just don't know anymore.he used to always wanna be with me. I understand we need our own space and I have been talking to other guys, I do love him I just don't wanna get heartbroken.so what's your advice guys.
