NYE rant- sorry it's long

Quick back story: I met my s/o in the beginning of 2017. We instantly hit it off. The only problem for me was his age. He's a few years younger than me, which naturally wouldn't be an issue- but his college friends (10+ male and female) make it an issue. His friends and him always go out drinking and clubbing whenever they hang out. This would be fine but I ended up getting pregnant 3 months into the relationship. He's a great guy that was ready to do the right thing but his friends keep pulling him into the party life. Early in the pregnancy I would go with them to make a good first impression. As my stomach got bigger, I became more uncomfortable with that scene. I stopped going out- but didn't stop him. I would suggest a night in drinking or playing games- anything except crowded things. I was always out voted 8by his friends especially his roommate at the time who knew he was planning on moving out for the baby. She made such a big deal about him moving out for the baby, telling their friend group that he was leaving her stranded and spreading bad rumors about me. At first he didn't want to believe it, but she continued to make the situation worse even after he left. We've had conversations about that particular situation several times and he agrees with me- that moving out for the baby was best for us and she was being inconsiderate. The picture attached is from one of our many conversations about his roommate. But now after talking about that, he opened up that his friends don't really like me. They feel like I'm stand offish and rude. When i tried to defend myself he just responded "Theyve been my friends forever, they wouldnt lie to me" Most of them have only met me pregnant at a bar or pregaming, which isn't the most exciting thing for a person who can't drink. At this point, I'm 6 months pregnant feeling crazy and hurt. So I brought some on my more out going non pregnant friends out on seperate occasions- so that they could get a feel for this friend group. The consensus was mutual, this group of people were clicky and not friendly to them either. My friends would try to start conversations with them but get shot down. My best friend tried talking to my s/o about her experiences with his friends and he admitted they could be immature.

Fast forward to NYE weekend I'm now 8 months pregnant.. my s/o told me about a week ahead of time that his friends rented a house in the city for the weekend and I was more than invited to the day activities but could go home during

the night activities. When he first told me that, I was low key pissed but let it go. I told him I wasnt going to go, thanks for the offer and I would just stay home alone. And that was it. I stayed home all NYE weekend by myself - not even a happy news years text. I'm trying to be understanding and positive but I feel like he's friends trump all. I keep reminding myself that he needs to get this out of his system before the baby comes. Am I wrong for feeling some type of way?
