Should I break up with my boyfriend?

I am thinking about breaking up with my boyfriend because his family acts funny towards me like they do not like me.I cannot understand why because I never disrespect them or talk out of the way.His mother acts like she has a problem with me way before I even met her,after I met her she was acting nice and said I was a nice and pretty girl and that he needs to keep me(at least that is what my boyfriend told me when I asked him what his mother thinks of me.I also met his father his parents are not together anymore.I never met his brother before because he was in another country for awhile but talked to him over the phone quite a few times ,he seemed nice and was being very friendly.My boyfriend was over to their house one night and I called because he ask me to,his cell was off,his sister n law answered the phone she was acting snooty. I never met her before and then later we met she was acting so funny I was ready to leave because I did not like the way she was acting.This was my first time meeting her.His brother who was so nice and friendly started being very mean and rude.My boyfriend is over to their house right now he spend the night there last night I called my boyfriend cell and to my suprise his brother picked up and he was so rude and cold,he told me my boyfriend was asleep.One thing I do know is i am a medium brown complexion like a toasty peanut brown complexion and he always use to talk about fair skin girls,one day I went to see him when I first met his mom he pick hand up and told his mom I just love her complexion.One day I talk to his mom on the phone I told her I met her grandaughter,the one who is darkskin and the others are fair skin judging from what my boyfriend told me because I never met the others just this one particular neice.I told his mom she is so pretty she said oh well you have not seen my other grandkids(those are the ones that are fairer skin).My boyfriend has never took a picture with a black woman before untill he met me.of course we took pictures together.Im started to wonder if his mom is color struck and him too.Im confused about all of this.Im on the verge of breaking up with my boyfriend because I feel deep inside his mom does not like me and his sister n law n brother don't even.Iver never said nasty mean things to them.What I have done is put my boyfriend in his place plenty of times and I think his mom was around and she heard but he deserve to be put in place because at the time he was being disrespectful.His father also does not seem to hang around them that much at all and he call my boyfriend mom a phone christian.I do not know all that much about her.He tells me he loves me and want to start a family together,but I don't know because something is not adding up to me.He lives with his mom and their housephone was off.One night I receive a call from a strange number it rand once so I called the number back but it rang and rang and rang.I told him later I receive a call from a strange number he ask what it was I told him part of the number and he got quiet.I later found out it was his number because when I dial through they would not pick up so I got somebody else to call they answered right away.Im only calling the phone when he ask me to not just to be calling and im not calling constantly,so I don't understand what is going on.what should I do because I know something is not right I can feel it.He tells me will I still be with him even if others don't want us to be together.
