Torn Between Friends....

The last two days had been rather hard on me as I'm caught in a "little personal dilemma". (Okay, I'd like to refer to is as my dilemma for now as I am torn between two close friends right now and I'm not sure if ever I'll be able to be fair to both of them since I discovered something that can ruin them and myself if ever it blows over.)

Ok, let me lay out an overview, but don't expect me to name NAMES ok? Let's just say, my friends, let's call him, GUY and her, BABE have been in an off and on relationship for the last 2-4 years. While BABE seems to be at least ok with what is going on with their relationship right now despite the fact that she really is intent on getting married with GUY sooner or later.

I accidentally chanced upon a COMMON FRIEND of mine and GUY and he asked me, if GUY and BABE were still a couple because he almost always sees GUY in their neighborhood being "too friendly" with a neighbor of theirs (lets call the neighbor, BABE 2) I told him, as far as I know GUY and BABE are still an "item" and that's what he knows as well too. But he showed me some pics (shot from his cell) of GUY and BABE 2 kissing intimately as GUY was leaving in different times as the shots had different dates when they were taken, and to top it off, COMMON FRIEND had a casual neighborly talk with BABE 2 and he asked BABE 2 who GUY was (COMMON FRIEND pretended he doesn't know GUY) and BABE 2 readily said that GUY was her boyfriend!

Both COMMON FRIEND and I know GUY and BABE quite well. While GUY has had the reputation of having occasional flings with different women from time to time (including those online) and we know BABE is well aware of it. But it is just now that BABE 2 claimed that she is GUY's girlfriend too.

Now both me and COMMON FRIEND cannot tolerate what appears to be going on.... and I've had the chance to talk to BABE (about a lot of things other than what I discovered about GUY and BABE 2) three times in the last couple of days alone! I want to tell BABE but I wanna talk to GUY first (but of course, I can never be sure if he'll ever be completely honest to me about it even though we're friends too. I wouldn't be surprised if he'll ask to keep it from BABE, which GUY knows I can't or I will never promise!

(SIGH) TELL OR NOT TELL....
THAT'S THE PROBLEM.
