Im not sure if this is going to work out!!!

So since my BFP my SO has been a complete d!@k!

I don't know how to explain it other than he is making me want to seriously consider leaving him. I know that he's probably going through some mental/emotional turmoil in his own way but WTF!!

I can't stand his mood swings and discourteous actions. I am a very strong woman who would raise my child alone if I had to so leaving the situation is at the top of my list of ways to reduce stress. BUT I don't want to be rash either...

Is it normal for males to completely freak out after finding out they are about to be a father?

Please help!
