SO acting different ...

Christie
My SO comes home from work & hardly even talks to me. Its like im not even here. 
I feel like he doesn't appreciate anything i do while he's at work. I currently stay at home.. but i clean, cook, & make sure everything he needs done gets done ..  
Now when it comes to intercourse, his excuse is hes tired .. But that never stopped him before . How do i get him interested in me ?!
