Over-analyzing. Seems like a typical conversation between old college buds...talking about a drinking game perhaps. Maybe he was the life of the party. Wouldn't worry about it.
It sounds slightly suspicious but not anything you can really read as anything going on for sure. It sounds a little like she's trying to tease and he's not rejecting the idea completely, but guys do that jokingly too, so can't be sure. I don't think I would get riled up just yet, but maybe just find out a little more about their relationship in the past however you can without causing a scene, or getting too much in anyone's business the wrong way. I think it also depends is he wanting to do this with her alone, or with others too? Just from the above conversation I don't see much that points to anything for sure. Just suspicions it appears to bring with certain wording like his response to the tattoo still being in pen and the desire to play the cups game. The better question is does the other female know you are dating him and if so why isn't she respecting that. If not, why doesn't she know about you? If it's a friend thing they shouldn't mind having you along too for this get together.
I think you should Ask Him about it. It doesn't sound like anything. and If It's on his Facebook and you are on there i am guessing I don't think he would have that Convo. knowing you might read it if it was something bad. I would just Kindly ask about it. Guys do need there Private space TO AN EXTENT. and If they don't get that from you, you could loose him. But It doesn't sound Like anything. If she looks like a whore...then look into her background :D lol
Overanalyzing at this point. Of course, we don't know what is going to happen from now on. But at this point, it still sounds like friendship.
Sounds like they used to drink together.
But I didn't get anything above an Associates Degree, so I'm not that smart.
That's just old friends catching up.
If this worries you in any way you NEED to give your own self-esteem a good kick in the pants.
Leave it be and stay on your own wall and in your own conversations.
1.) he's a "boyfriend".
You're not engaged,
you're not married.
This is sooooo lame.
2.) yes, you're over-analyzing.
3.) and, you're a drama queen.
Act your age.
8th grade is over... & has been for a long time now....
Matching cups means to drinks as many shots as the other person(or just to drink the same amount) Well, if he was lying just to have a conversation it may be ok; but if he actually goes back to match those drinks you may need to worry. B.O.A.N if you love him just let it go. It will do nothing but create problems to discuss this. Boys will be boys. I wish the best of luck to you.
