Helping himself

I feel really bad when my fiancé and I have sex. He seems to make me orgasm several times, but he sometimes will stop and says there ya go, or will say you got yours right, good so we are done and stop. He used to pull out and cum on my chest or stomach but lately he isn't getting his at all when we have sex and he helps himself out when I'm not home. I sorta feel bad that he isn't cumming with me and tried talking to him about it but he just laughs. I tried saying it makes me sorta feel like he doesn't want me or if it would like to mix things up and try something new. He just said everything is fine... Any advice or thoughts?
