clues if he's married??

Best way is to go his house

for my case i manage to asked the HR department, lucky me i got a good friend there, but for guys i meet outside the work well thats a bit hard, if a guy purposely hides his wedding ring and declares that he is single, one of the option will be find a way to contact a relative, or a very old friend that he has grown up with, but if your seriously in to him and you really want to make sure, maybe you can find ways to contact someone with in his company who can help you get this detail.

Well, there are always signs.. Try looking out for rings or ring marks on fingers, and one will know if they are married.. haha =D PLus, taking secret calls, and always have to find excuses for things etc.. hehe ^_^ But for someone who's plain dating, it might be slightly harder to find out, for they have no real committments yet, and thus there's not much control over them, and the things they do.. THus, it can only be a matter of trust, or things they might have made us suspicious about

Check his fingers if he wears a wedding ring. Ask him you want to know or like to meet his parents. He is spending more while he was with you. Sometimes he has too many reasons when he failed to see when you have to date. Be very careful.

if he lives in your city and country I am sure you could invest on doing a background check, that is a safe way to find out if person has a history, criminal and marriage. If the person lives out side the country, there is not much you can do to find out, other then paying attention to what he says or does, look for signs in photos, wedding rings, pay attention to conversations, and behavior. If you have think he is married out of common fear, just pay attention to things he says. If you are just a jealous woman and that is your common worry then seek for relationships with people near by you and also work on your ability to trust too.
