"my friend said the kind of love i am getting from my mom and sister is not the kind of love i need."

listen to your friend, you are not a bother, stop thinking that, it sounds to me like you have been trying all your life to get some recognition or acceptance from your mom and sister only for it to be thrown back in your face at every turn, it is time to turn around and think about what they have/are doing to you and your family,

the only person who can stop all of this is you, you know this, your hubby knows this and your friend knows this, listen to what advice you are given, sure you have loads of what ifs, if only i, if they would just's for example, but at some point you are going to come to the realisation that because of their (mom and sisters) actions your own family unit is going to fall apart, you have to make a choice, if not for your own health then for your hubbys and childrens, let them (mother and sister) ride the what if, and if only roundabout.

move on and build your own family, you really dont need then around causing you this much pain.
