What am I supposed to do?

For as long as I can remember, I've always been struggling in making friends. And, now It's even more complicated to do, BUT, thanks to FiveM and other games like Roblox I've been able to make some friends for the past few years!

I've had the same friend group for 5 years but ended up leaving them behind for my own good, and I've made a new friend group with people older than me (It varies, from 19 to 32).

 We were a group of 5 at start, but ever since we went on a new roleplay server on FiveM they met new people and made a new friend group, and since I took a pause from roleplaying because it was becoming too much for me, It's like I'm not a part of this friend group anymore.

I told them I was sorry because, well I just felt bad for taking a pause from a game for still a long moment and not coming back yet and they all said they weren't angry at me and all but it feels like they are angry with me.

Among those 5 people (4 because 5 was by including me) there's this one guy and we get along very well, and a girl who's 32, I really like her she's nice and all, I know she's not angry with me about this situation and she might be the only one, but she's a part of the new friend group, kinda left me behind.
And so, if I'm not counting him in (The guy I get along with pretty well, because he also took a pause but said the RP server was becoming shit and our 3 friends were also not being themselves anymore) we have 3 friends who look like they moved on from us and created a new friend group with new people they met in the roleplay server, and I feel left alone, and I feel like It's my fault, but at the same time I don't know what to do, I don't want to leave them behind like my old friend group, they're nice.

But there's one thing I'm angry with them about, and I didn't tell them that because they were supposed to already know this because of things that happened to me and that they know really well, I'm Christian and really into religion, and talking about s*x and everything that goes around this topic makes me disgusted, disturbed and REALLY uncomfortable. And EVERY conversations they have or in EVERY ducking stream they make they talk about s*x, or joke about s*x, and It's making ME and the guy I got along with pretty well REALLY uncomfortable. He's religious too. We do not like this topic and It's like they can't respect that. It's like they never truly respected us but instead tolerated us. 

I feel like I'm shit. 

Please, help me, reassure me, anything.

Thank you to whoever red all of this :)
