Long distance boyfriend doesn’t communicate much on weekends. Is that weird?

So we normally talk a lot through the week but once the weekend comes it’s like he’s non existent and I don’t understand why? I understand he has his activities and friends but it’s just so weird how we won’t talk at all during the day and it raises an eyebrow. He treats me with a lot of respect and I trust him but sometimes I get mixed feelings when he pulls off this stuff. Also, he brings up the fact a lot how he’s 30 and not married and I wonder if he’s just trying to fill that void of being single since all his friends are in relationships. I don’t wanna throw hands and make accusations but I just feel strange how a lot of his friends don’t know about me but his family does. According to him I’m the first girl he tells his family about. I also just need some lady advice because I’m struggling in finding some peace. It could be that I’m also over reacting. I also want to mention one big thing that has really really bothered me. At the beginning of our talking stage he admit he was meeting and talking to girls through his friends and the parties they have and he ended up hooking up with one of them. He’s always told me he’s not that type of guy but I in a way caught him in not telling the truth. I May have no right to be upset at him but it really bothered me even if we weren’t together. It was the fact that he said he needs to be very close to someone and then went against his words. He’s not like any guy I’ve talked to and I truly feel he’s a good person but I do have my doubts. He drives down 12 hours to see me and spend time with me and even plans vacations and all. I just can’t help but feel the way I do and why I do. Advice please :)
