I love that my son is bonding with his dad and everything but now he never wants to be home with me. and when he is home with me he always expects us to go out and do all these fun things. Which wouldnt be a problem if i wasnt 7 months pregnant and if it wasnt hot as hell outside. Like I have plans for us just not everyday. Its just really hurting my feelings. :(
