Not enough quality time with my partner??

Hey, so I've been wanting to ask my fellow ladies a question.. I don't know if I'm being a b*tch or if he's just not into me anymore? So help me please. How much time with your partner is enough or not enough or even too much? I work all week (I work with children) and I come home to my daughter. So kids kids kids kids kids all week, my partner and I don't live together so it's not like I come home to him and my daughter (who is his daughter as well, btw lol.) We are both off on weekends and NEVERRRRRR hang out anymore really. Haven't been intimate in 2 weeks and he's not phased by it. Am I being a b*tch by being upset or worried that this relationship might be ending or am I right, I'm not getting enough time with my partner????
