Am I in the Wrong....

I've been living with my boyfriend for approx 1 year now. In February, I caught him sexting not 1, but 2 of his female friends who also happen to be married to friends of his. He was out of town for work while this happened, and while he was gone i hardly heard from him at all.

I confronted him, he apologized and said it would stop. Fast forward a couple months. Caught him still doing it....very explicit messages, and some of them sounded like he had physically cheated on me with them (i later found out he did have a threesome with them before i had met him). he swore there was never anything physical with them while he was with me, and again promised he would stop sending the sexual text messages. Needless to say I don't have complete trust in him after catching him doing it twice.

he still does talk to them, but i think the sexting has stopped. i obviously don't like these girls, and he knows it. the entire time we have been together he has hung out with them maybe 2 or 3 times, and i have always been with (even after all that happened, i sucked it up and hung out with them because he wanted me to). to me, hanging out with someone over the past year and a half doesn't equate to "good friends"

well now one of them is having a birthday party for her son, and we are invited. i don't talk to those girls, i have no interest in being friends with them. I told him I don't want to go, and would prefer if he doesn't either. of course he got mad, sad she's his friend and he's going, regardless of my feelings. now we are sitting here not talking to each other.

Am I wrong for asking him to not go? yes i know it's not a one on one thing hanging out, but him being around them (both will be there) and having communication with them makes me uncomfortable. he's done nothing to help get my trust back - it's all my fault and i shouldn't have any issues with them according to him. so am i wrong, or should he be more considerate of my feelings and respect my wishes to not go given what's happened over the past 8 months?

Tell me why you stay with him? What loving actions does he bestow upon you that compels you to stay with someone who disrespects you so?

Dump him immediately! What are you thinking?

He is most probably not 'just' sexting these women. There is a very good chance he is doing much more than that. Not only that, but these are the wives of his friends which makes it doubly inappropriate behaviour. What sort of a person is he? Why would you want to be with someone who is so deceitful, not just to you, but also to his friends?

There is no future in this relationship that I can see.
