Am I overreacting? 😩😩😩 UPDATED**

Okay so my SO is a very touchy person. Constantly poking me with his meat and wanting to have sex. The last few days, his best friend introduced him to his fuck buddy. They’ve been messing around for a few days and within that time frame, my bf hasn’t touched me. Hasn’t wanted to have sex and has been gone with them a lot. Like, everyday he’s off of work while I’m stuck at home. He’s been best friends with this guy for years, we all have known each other. They got kicked out of school together because they’re honestly just immature and stupid when they’re together. A few days ago, he admitted he’d have a threesome with another guy (BUT NOT WITH ME). And it honestly hurt my feelings. A lot. He’s never said anything like that to me before. Ever. Like I understand if he wants to have a threesome as a fantasy because we all do, but I wasn’t included in said fantasy. It didn’t come off as a red flag until I met this girl yesterday. He said they were coming over and I made a stank face. I honestly just don’t like meeting new people because I have social anxiety and sweat so bad. He said “why don’t you like her already” and got defensive when it really wasn’t anything personal. When they were here, he didn’t really talk to me and was around his best friend and his fuck buddy (we had other guests over too so it was kinda rude of him). He then brought our daughter out, which at the time I thought was really sweet but then he made a point to say “She has to meet her.” Guys, this woman is practically a stranger. I met her once for a few hours and she *has* to meet our daughter? Maybe I’m overreacting with that part but he has never said anything like that about anyone else. Not even his family. I shrugged it off. Then when they left, they dabbed each other. Guys, if I dapped with a random man I was spending time with for several days in a row, he’d be flipping shit. He said “Why didn’t you talk to her” and I just explained I was talking to our other guests. I even offered her a hit off of my bong so I wasn’t rude or anything. Just preoccupied. He was upset that I didn’t talk to this stranger that was at our house 🙄🤦🏼‍♀️ Why? Why does it matter? She’s just ****** fuck buddy, why do I need to befriend her? Fast forward a couple of hours and I told him how I wanted to go to the gym. (Which btw, I can’t unless he watches our daughter for an hour because she won’t take a bottle, and he just won’t). My boyfriend has always said he loves thick women and that I’m perfect. He replied “work on yourself”. He has NEVER said anything like that before. This girl is half my size. If he really wanted me to lose weight, okay he could have told me months ago when I popped out his daughter. Why has he made me feel beautiful if he thinks I do need to work on my weight?? I struggle with body dysmorphia and eating disorders. Since I’ve been breastfeeding, I’ve been taking in calories and have been doing good with it. Now, I really just don’t want to eat. I know, dramatic right 😅 But like I said.. I’ve struggled with this for years. Before I went to bed last night, I made it aware I was going to sleep and he didn’t say goodnight, kiss me or anything. Guys, my SO is a very touchy person. That’s why all of this is such a red flag to me. This isn’t like him and he didn’t start acting this way until he met this girl. He’s also been on edge the last few days and just hasn’t been sweet like he usually is. I really don’t know what to think honestly. My SO is not the cheating type and I do believe he loves me, but this whole ordeal just seems off to me. He has spent everyday with them this week and is planning to see them again tonight. And where will I be? Stuck home, taking care of his daughter.

UPDATE: He just woke up and is already leaving. I’ve been awake since 6AM with his daughter and he’s going to look at cars with his best friend. As soon as his best friend walked in, he asked his him where his girl was at.

UPDATE 2: So I brought up everything and he’s denying he ever said anything about threesomes. Saying that I dreamt it and I’m overreacting. Saying that I misinterpreted what he meant about the gym and when I wouldn’t accept his “apology” or whatever tf it was.. he said I was just being a nagging bitch and left again.

UPDATE 3: So we talked about a lot and he said there is absolutely nothing going on, that he was just excited to show our daughter off. He said he didn’t know his girl was going to be with them when they went out to eat. Said that with working and being stressed, he just hasn’t been “there” and is focusing on making money and flipping cars. (He flips cars with his best friend and they spend a lot of the time working on them.) He swore up and down that he’d never hurt me, and that he loves his family. He’s been home more and hasn’t hung out with her since they came over. Honestly, I’ve been in such a bad place mentally, that I think I was just thinking way too hard about it. We have had sex twice since I originally posted so that’s a good sign I guess. He also said if I wanted to snoop through his phone, I am more than welcome to, but I trust him so I’m not going to. He said I misinterpreted what he said about the gym and was referring to me getting a bigger bum, which I’ll admit I’m basically ass-less lmao. Even though he says it’s huge.. I know it isn’t. He said he really doesn’t remember talking about threesomes (he smokes weed and says the dumbest, gayest shit when he’s high and then forgets it 🙄🤦🏼‍♀️). So we’re working on communicating better and I’m working on myself. I haven’t been this low in years and it’s really effecting the way I perceive things.
