Totally alone

I move across the waters to be with my man, I move away from all my family and friends, take my children away from their friends and family so I could be with this man, yet somehow I am completely alone, I don't feel wanted by him anymore, his family always come first with him, I really don't know what my status is here anymore.  
I come on just for company, hoping and praying somebody will relate to me and to no avail.  I just want to be wanted by him and I don't think he does anymore.  I just don't know what my purpose in life is anymore and am slowly sinking deeper.  I love my children whole heartedly but I can't help but think they would be better off without me.  What mother takes them away from their dad for their own selfish needs.  They are the only reason I get up everyday, otherwise I wouldn't bother.
My dad passed away last year and I often wonder what it would be like to be with him, I need his words of wisdom but can't have them anymore.  I know where I live and I know my name, but in all honesty don't know who I am anymore.  Lost girl
