Pissed off!!!!!!

Do you think it's right that I have to go to work and boyfriend encouraged me to take on overtime so we have the money as we're ttc. Yet he doesn't tell me he's going to a concert tonight with all his friends and there girlfriends! Something fishy is happening and I'm not agreeing with it! I'm beyond livid. He tells me that I'm not gonna keep him from hanging out with his friends mind you in the 8 years we've been together I have never ever even tried. He went to a graduation party last night and when I walked in hugged and kissed him some girl asked who I was I said his girlfriend and she walked away with her friends and was laughing with them!!!! Made me feel totally uncomfortable and uneasy. I don't know what's going on with him but I seriously am about done with the bs lately!!!!!!
