kinda long, sorry

I have a boyfriend and all is well, there is nothing wrong with us and he already knows about all of this because I tell him everything. I have a lot of guy friends because I grew up with guy friends, I never hooked up with them or anything like that I never was like that. I genuinely just have guy friends a little more then girl friends. Whenever I hang out with guy friends and I meet one of their guy friends, I feel guilty for just having a conversation with them and laughing and no it's not flirting we're just having a conversation like normal and just laughing at jokes and stories and I'm never alone with them, I don't like to be but I always feel guilty after as if like I did flirt with them when I know I didn't. I don't know if it's just my guilty conscience because I'm just scared to lose my boyfriend. I don't want to be scared of making new friends, am I just being too kind to them or something? I'm not doing anything wrong but I feel like I am😞
