Where to draw the line between girlfriend's guy friends?

My girlfriend and I have been dating for almost a year. It's recently been bothering me how close my girlfriend and her one guy friend is and it's hard to distinguish between being too controlling or if I'm just letting her walk over me. First off, I would like to say that me and my girlfriend dated almost 7 years ago and rekindled. So we have a kind of bond that doesn't really come and go. She told me that her guy friend has been friends with her for 7 years as well. I'm a bit skeptical of this whole situation and I've made a post about this before here on gag but I feel I wasn't broad enough on the questions I asked nor was I clear enough on the details. After about a few months of dating her I had never heard of this guy friend, up until the playoffs with the Steelers this year when she went over with family to his house. After that it's like she instantly became best friends with him again; I don't know if she lost contact or something but they definitely weren't texting or anything before that. Since then I've heard his name come up quite often, they recently just started following each other on facebook and twitter which made me question if they really had been friends for that long but I ultimately decided to trust her. I have no idea how much they text because she deletes text messages. But I do know that they facetime every day I've seen the facetime duration up to 2 hours long on some calls. They snapchat everyday, and I see his name pop up on her social media almost every day as well. I've been asking her to meet him since the day I found out about him but I haven't met him yet it has been a few months. She said they used to hang out almost every day before we even started talking again. But communication must have stopped when we started talking or something. I'm wondering where do I draw the line? I mean I am trying to be understanding but I can't help but be bothered by this. Is this normal?

I would like to add that I love my girlfriend, I trust her very much so. It's just I'm curious to see other people's takes on my situation. I'm trying to be as understanding as possible in this situation but I find it very difficult at times because I feel he is asking too much of her time. It also makes me feel like I'm not satisfying her needs enough and that she has to look elsewhere for them in a platonic way. I don't know really what to make of all of it.
