I give up

This is less about baby making and more about how I think Woody and I will be done soon. I think he is in love with another woman. I know I am a little emotional because I am on my period and that means yet again Woody and I failed to make a baby but I feel like he is hiding things from me and that now that he is back in South Carolina that he is going to go back to being with his old girlfriend Sara. I just don't know what to do. I know I can't stop him from cheating or leaving me for her but it is killing me. I am not even sure if he loves me right now or is just staying with me out of obligation since I moved across country for him. I am so depressed. I know they talk about thinks that are not what one married person with two kids and one person in a serious relationship and trying to have a kid is supposed to talk about. I really don't know what to do. I guess I will just have to bury my head in the sand and hope he doesn't leave me or hope he doesn't sleep around and give me a VD.
