Hey guys, I am new here, but I have had the same type of situation before. I am sorry to hear that. He actually said that he was no longer attracted to you, or did he just say that he didn't want to have sex anymore. See, some men have trouble comprehending what actually is taking place inside a womans body; leaving them confused and scared. First off, if that is the case, maybe you two should sit down together and do some research on this particular situation (sex during pregnancy).
On the other hand, if he is being an ass, you don't deserve that. Was the pregnancy planned. As far as the porn goes, I agree w/everyone else. That makes you feel 2nd best, and makes your self esteam go way down. Well, maybe things will get better, and always know that you have people like us to talk to at anytime. Good luck!!!
