Is it lying or just not saying?

You slept with another guy, and one of your kids is from someone other than your fiance? You should tell your boyfriend. Don't lie. You skrewed up...many times apparently, but you have some precious kids and you have a boyfriend who hopefully loves you. Tell him the truth, stop lying, yes...lying. Keeping something you know someone should know is as bad as lying, may as well call it the same thing.

And stop making huge mistakes that have drastic consequences.

Yeah...it is considered lying! i agree with ^^^

Hmm. If you aren't ready to tell, than you can't force yourself to say it or it will come out all wrong and hurt worse...but, it is also better to just say it now instead of risking having them find out the harder way.

As far as I'm concerned there is blatant lying and there is witholding the truth. Blatant lying is when you are directly asked something and are false or dishonest in your response. We are all entitled to have our secrets and to have a personal and private side to our lives and personalities, and we should not be made to feel bad or guilty about doing so.
