I would not do it for my significant other, married or not married. But ex boyfriends who are now supposedly just friends - those can be a source of friction.
you should marry someone because you love them
no
Yes!!
I'd say this is a big no-no unless you are friends with the husband as well and he understands, if this is so a simple friend hug will work.
If you trust that your friends will not tell anybody, then go for it!
someone you like and can give you happiness and loves you
If I don't want to be friends with someone I simply avoid them if I can, or just politely ignore them if i can't avoid them.
You should never move in with someone if you aren't married.
NO BECAUSE THE MARRIED WOMEN CAN REALLY BE FAITHFUL TO HER HUSBAND
Lives and friendships do change when someone is married however, they should still be able to converse with you and possibly get together once and awhile. If this is not possible spend more time with your other friends although they cannot replace this other friend it is time to move on. Friends will unfortunately come and go throughout your life.
A certain someone can unfriend friends who have inactive accounts on Facebook. It is a matter of personal choice.
Yes Can you elaborate more on why you think its ok?
