So I'm in a relationship we been going together for 1 year 2 months. I regret not getting to know his family cuz we wouldn't have a child. Don't get me wrong my sons the highlight of my life. I hate that he takes up for his siblings and all that more then me but he be the one talking bad about them to me. I don't understand how you can say you there for me but whenever somebody in his family call him he break his neck when I ask him something he bullshits. It's like me and my son aren't priority at all am i wrong for not  liking his family let alone being near them.
