@Irishlady31,
There is "nothing" to suffer over. He is everything you "don't" want. You're pissed because you tried to play hard to win and lost to another girl.
Truth is you didn't lose to her at all. He doesn't care about her, didn't care about you, doesn't want relationships just thrills.
With every negative there is a positive you sound as if you don't have faith that you can have thrills/adventures with your husband.
Every man has fantasies as well. You'd be surprised.
Everything also has a lesson to learn.
I wonder how you would feel if you found out he'd been having an affair and loving the sex.
I can imagine how you would feel.
If you have an STD, you "have" to tell him whether you lose him or not. You can't play with someone's life.
To be honest with you. I'm not one for liking cheating. I am one that says if you feel you need to cheat then you don't have what you want in your life, walk and then do what you want.
But you keep "claiming love". He's everything just boring sexually.
Like I said, I bet he's not, it's what he is used to from you and over 30, you are allowed to explore should explore but with your partner. Don't underestimate that he can't be involved in that.
