I want off the roller coaster too, and I also want to stay in my marriage.
This. So much this. Thanks for your response. Though I feel bad that you have had to endure so much hurt, it's also reassuring to hear that someone has had similar circumstances.
The pushback on female 'friends' really bothers me a lot lately. He is super intense with his contact with these women despite knowing them for a very short space of time and bends over backwards to compliment them, be attentive to their needs and make himself available as emotional support. He will also give them gifts and refuses to acknowledge the message that all these things send to a woman you just met. He claims he is just friendly and would do these things for anyone but I don't see any of this behaviour with male friends. They are lucky to even get a text back from him half the time. In fact, he often avoids talking to them deliberately by not answering calls or messages but never when it is a woman. He has admitted on occasion that even though he doesn't intend to act it boosts his ego that these women may have feelings for him but then backtracks later when it is convenient. He says that he shouldn't need to change who he is and that he wants to just behave however he wants and then if they say or do anything inappropriate he will 'deal with the situation'.
No matter how hard I try to explain, he doesn't seem to understand that creating this emotional intimacy and taking so much energy and effort from our relationship to seek approval from these women hurts me. Or that him 'dealing with a situation if it happens' isn't enough. I'm fine with him having regular, normal intensity friendships with women but him still going out of his way to do this hurts me as I feel he he isn't trying hard enough to avoid repeats of the drama we've had previously for what I can see only as his own selfish reasons.
And aside from my feelings on this, what about these other women? He is sending them all the signals that he is interested and possibly encouraging them to fall for him to get a feeling for himself, knowing he will never act on it. I have less sympathy knowing that they are aware he is with me and still soak up all the attention but can see it must be somewhat confusing for them too.
We are having some relationship counselling soon so I'm going to try to bring it up there and see if we can set some boundaries with which we are both comfortable. Although the counsellor has said she feels his thinking is the main issue and that until he has had individual help she thinks it will be difficult to change a lot of things so I guess we are in limbo a bit with it all.
Anyway, it is good to have support from someone who can relate so thank you!
