Search Results: good relationship with your boyfriend girlfriend

Alright so when my boyfriend (Lets call him B) and I were on our second date we went to starbucks, and his best friend (Lets call him D) was hanging there with some people (so I met him for the first time, not sure if this was planned or not).
We ended up staying and hanging out and since we all share a love of gaming B prompted me to share my ideas for my game room when I get my own place. D then shook Bs hand (I'm guessing because he was impressed and was congratulating him for finding a gamer chick, haha). So I'm pretty sure I had already gained his approval. Since then the three of us had spent a good amount of time together, but last night we all went to a hookah bar, then ended up going back to Ds house to drink.
After we all had a good buzz going we were outside smoking, and D was like "B, B, B, listen to me, you could do anything in your life but nothing would be better than this girl you have here" B was kinda distracted by Ds brother when he said that so he didn't really say anything to it but he smiled and gave me a squeeze. Then later when we were pretty drunk D said "I know it's too soon but I would be very happy if you an B ended up getting married" I'm not sure if B heard that but it just shows how D thinks we're good together. He said other things through the night but the details are a little fuzzy after awhile haha. Anyway I'm wondering what my boyfriend thinks about this, we kinda talked about it and he's happy his friend likes me but I don't know how important it is to him. I know everyones different but in general, how important is it to guys that their friends like/approve of their girlfriend? Also, the stuff he said was pretty intense so is that something he may worry about? His friend wanting to steal me or something? Is it bad that D and I get along so well? If he didn't hear the thing about D being happy if B and I ended up getting married he might not know that he respects our relationship and really wants me to be with B.
Thoughts?

My boyfriend has been consistently obsessing over this one girl. A female friend who he'd been seeing for ages without ever telling me of her. We've been dating 3 years and I think it's odd for a guy to simply meet with a girl you don't know behind your girlfriends back. I just recently found out he'd been searching for her every single day on Facebook and I was really hurt and upset. Why would you search for someone if they're not in your thoughts?
It's not the first time I've felt uncomfortable with how he is over her so I suggested a break from each other. He says he only wants me and no one else but this is his first relationship. Everything else is perfect and I adore him but I feel like I can't trust him. He's always secretive about her and always gets a guilty look and denies everything even when I know he's lying.
But now I'm feeling guilty over arguing with him and suggesting a break. It's our anniversary tomorrow and all I want to do is see him but I don't think it'd be a good idea.
Do you think I'm over reacting or fully justified in what I've done?
