Struggling in relationship

I’ve been dating this guy for 6 months. He’s a really great guy. But, I feel like my anxiety gets in the way so much. He’s always been into making new friends and has a lot of friends who are girls. Even though he says I’m the only one I worry that I’m not.

I also feel that are relationship has kind of taken a turn. I feel he doesn’t message me as much and I know he’s busy and I usually wait him to respond unless it’s an emergency. I feel like we are strained and I don’t know what to do? I’m still a virgin and we have came close to having sex but I feel I am just not ready or I feel the mood and the situation isn’t right.

I really do love him I just feel that I’m bad at showing him how much I really do love him.
