My boyfriend and his female best friend, cuddle.

Me and my boyfriend have been together for 5 months. My boyfriend and his best friend, who is a female, cuddle. Like when they watch movies. I told him it makes me uncomfortable and he did stop. But I found out it happened again and he said it’s cause she was sad over a breakup. I should also mention we are long distance. What should I do?
