feel like me and my so don't agree on anything and now he's being a jerk cause I asked if he would be okay with me going to Greensboro to see my friend in April and he felt like I was trying to meet up with an ex who lives in Alabama now. then he says why would I want to go out of town pregnant. so I said that and he asks how I know he's in Alabama and accuses me of talking to him behind his back. I'm so sick of this. I can't do anything fun because I'm pregnant and he's the one who catches the attitude. I don't know what to do to show him that I'm his and I'm not going anywhere he just thinks I'm just like his ex and that I'll just hurt him like I'm not them! I really want to strangle and the castrate him in that order then maybe he'll have a reason to think I would cheat since he wouldn't have a fucking dick. asshole.
