Today I woke up feeling blue, idk if it has anything to do with my pregnancy or what. I am very emotional, a few days ago I ask my husband  if he love me? His answer was yes them I ask are you IN LOVE with me? He responded with a sometimes. I don't know how to feel about this. We have a 2 yrs and currently expecting baby #2, our relationship has been challenge so many time in the past like any other relationship. I learn what pain was with this man and I don't think I can ever be the same. But at this point in my life, I feel like I have gave him my whole life and the treatment I have received from him like wtf do I deserve this? I seriously waiting for him to get home so I can tell him that we need to come up with a plan to separate soon. Am I might overreacting to my feelings?    

- I love my husband so much, however I can't love him more them what I love myselft. It took me yrs to learn this.
