So he has to stay an extra hour today at work so he won't get off until 7. But I honestly don't know what to believe anymore. Like he told me his ex gf who he was with for 2 1/2 years , just broke up with her bf. He told me that friends from high called him and told him. He has no calls from anyone and no Facebook messages to back this up. I told him before I don't want him talking to her. She is a whore who cheats on everyone and she has no morals and wouldn't Mind trying to hook up with my bf. This is the same girl who a year ago told me not to get too comfortable because her and my bf were just taking a break so they can sort things out. If something is going on I want to know before I have my son. I don't want him there if he is lying to me and talking to her behind my back.
