Guys, should I show up at his work and demand an explanation?

I know this must be tough, but definitely do not show up at his workplace. It is very likely that he would feel humiliated in front of his coworkers to have his personal business put on display. He might even get into trouble with his boss for bringing personal stuff into work. He will probably be angry at you.

My advice is to assume that he doesn't want to see you any more. You have already sent him a text and he hasn't replied. If you keep trying to contact him and he doesn't respond, you will just feel more and more frustrated and disrespected. You know you deserve better than having to chase a guy. I would put him behind you and find a better one! Good luck!

That's a big Neg-a-tory.

If you do this, you will become a fireside beer story for this guy. You'll be "another one of those crazy women" - because I guarantee if you do actually do this, he will run from you like a gazelle that just spotted a cheetah.

My advice to you is this: Give him ONE more call (or e-mail) - and keep it civil - it's okay to communicate you're concerned, but avoid being critical. If he doesn't respond, then let it go (for now). When he comes back to you (if he comes back), that will be your turn to control the situation.

Obviously, this guy likes to play games. If you don't (and most women don't), than don't continue to stuff quarters into his machine as it were. I hate to tell you this, but this guy sounds very immature, and probably not worth your time.

NO.. You'll just scare him and be more distant with him.

First of all.. The environment to have a confrontation with him is completely wrong.. Come on now.. A public place like his work place, so you could embarrass him?

Second.. You're not giving any info on how close you two are. If you're not married, and he didn't cheat on you.. You have no right to DEMAND an explanation form him.. He doesn't have to give you an explanation, and by "demanding" an explanation.. You're making yourself look really controlling and needy which will scare him away.

If you wanna talk to him, catch up with him after work, say hello and ask him how his day was.. And then eventually just say something like "I haven't talked to you for a while, how's it going?"

No, you should not. It makes you look immature and crazy. He's basically told you he doesn't want to see you anymore by not contacting you in 2 weeks. Was that mature of him? No, not at all. But you need to just move on and forget this loser.
