Awww.. I'm sorry you are going through such a rough time.. I have been in your shoes.. wanting someone that obviously does not give a crap about me. There are two books out there that helped me tremedously.. "women who love too much" by Robin Norewood and Codependent No More by Melody Beattie. It helped me see why I chose the people I do and helped me to learn how to set boundaries for myself and not let people treat me like crap.
he said he could never spend the rest of his life with this girl and just wanted the baby to be out already.
This statement alone tells me that this guy is a worthless POS and not worth the time nor energy that you are spending crying over him.
If I were you, I would either block his number or change yours.. No contact with this guy is the only way that you will be able to move on with your life.
