I see.
I think that...we all tell small lies....to make people like us. I don`t know how you feel about it - but it seems to me that if we realize that we are good enough as we are we don`t need to tell any lies. The truth is enough.Is good as it is. But i personally dont think its that bad. like: what the heck, are you telling me that if he knew you WERE kissed b4 and had boyfriends, he wouldnt go out with you?!
I think this is no big deal, i understand that for both of you it
is. i think that if you, with Gods help - will stay together for more years - you will look back and laugh and this. i know now it hurts and all that. i understand much better what you are talking about right now. you cheated once and now you dont want to cheat second time. it all reminds you.
anyways you got your "punishment" by being called names etc... so - now - does he forgive you? if he really loves you i think he will.

Even if it takes some time.
Good you are in therapy. good luck with it
