Relations

I'm not sure why I've been thinking about this a lot lately, but I noticed my boyfriend has been distant towards my family. When we first met he was great, he loved being around my family and always attended family outings. As the days go by and the more we are together, I noticed that he doesn't seem to care for my parents anymore, or my siblings. The last time he's seen or talk to them was February. He couldn't even text happy mothers or Father's Day to my parents, yet alone his. It's as if he doesn't know them and never met them. They never did anything to him he just stopped coming and caring I guess. He stopped coming to me as well. But I see that I care for his family so much and I'm always around. I respect them so much as well, even though their lifestyles are messy(different). I take care of his sister whom is like a mom to him when she's sick, I help her clean around the house, and pick her up from dialysis. I pick up his nieces and nephews and hang out with them since he kind of dislikes children. Pretty much anything I can do to help out, I will do it. But I noticed he treats my family like crap. I always valued my family and put my family above everything, but him treating my family like this kind of makes me lose feelings for him. I always told myself that whomever I dated will treat my family like his own, but he doesn't treat his family well either. I was wondering if the way your man is or a man is towards your family, does it play a role in how you feel for them? Or if you guys have anything to say about it, please do.
