Feeling Salty

I can already tell before I've even started writing this post that there will be a lot of judgement but I don't care, I need to rant. Last night my husband wanted to go play D&D with his friends. I really didn't want him to go because I knew he'd probably drink and not come home and I hate sleeping alone. Plus, we have a 9 month old son and weekends are the only days I'm able to actually be by myself for at least a couple hours while my husband watches him. Despite these thing, I let him go anyway because I don't want to be that wife that makes her husband stay home and be all domesticated and shit. Earlier in the day when he first mentioned it he said it was going to be a group of his friends and their wives so I was like "hey, why don't me and [our son] go with you and hang out so that we can be your DD." He kind of brushed off the question and later went upstairs to make a phone call. When he came back down he said that the plans were changed and it was just going to be the guys. I can understand that he doesn't want his wife and son there but I'm getting so stir crazy here. We just moved a few months ago and I have almost no friends and no babysitter. The one friend/babysitting that I do have left to back to her hometown for a couple months only about a week after I met her. I just want to talk and socialize with other adults for a change. When he left he promised he would only drink a couple beers as soon as he got there and then come home after their effect had wore off. About an our after he left I called to see how things were going and he told me that he had just got there. Keep in mind, his friend only lived 15 minutes away. I have no idea why it took him so long, he said he got lost, but what I did know is that there was no way he was coming home that night because it was already 11 pm. I called again around 1 just to confirm my suspicions and when I asked what happened to two beers he said that they turned into jager bombs. I got kind of upset but kept my cool and just told him that if I had went with him then I could have been the DD. When he got home I wa seven more upset because he let it slip that the other guys wives were there and he had lied to me about plans being changed. I'm still kind of upset because like I said before, I'm at home all day and I just what some human interaction. He has never wanted me to hang out with his friends, even before we were married and had a kid. Come to think about it, I've never even met any of his friends, none of them. It's like he just wants to hide me away so he can have a separate social life while I don't have that luxury. He's met all of my friends and we've hung out several time. I want to hangout with him in social situations with other adults but when I mention that to him he just says "yeah, we can hang out with your new friend and her husband after she gets back." Why does it have to be my friends? Why can't I be a part of his social life for a change? Sorry for the rant, I'm just so upset.
