husband sexting close friend
i am 24 and have been married for over 2 years. since last fall, my husband has been sexting a very close friend of ours/my family who is also the mother of one of my best friends.
i caught him in spring. he lied about it and said it was only once. they had been doing this almost weekly, and it continued after i caught him up until a few weeks ago when i caught him again and finally threatened divorce. even then he still lied.this is not the first instance of this, however it hurts the most. he has attempted to meet with her to hook up.
he has told me that it's my fault regardless of how much i have tried to fix this. he says the only solution is group, but he doesn't understand that there needs to be trust for this to be an option. he would look me in my eyes and lie. i even saw a counselor because i became so convinced that it was all my fault. through these hard times and more, he was still doing this.
i am giving our marriage one more try, but my conscience is telling me to leave. i have no trust in him. his words have become meaningless. he would even sext with her while we'd be out with friends and he'd be standing right by me.
i don't know what to do. i love him so much, and when things are good they're great, but i don't know that i should be with someone who would hurt me so much. he assures me he wouldn't actually cheat, but i don't believe him considering he tried to set something up.
and this is such a close friend. i sent her an e-mail telling her-and i'm paraphrasing-to beat it.
this is just a summary of it all. what should i do? am i an idiot for still staying?
