SO has odd views in relationship

Every so often it will come to my attention (in various ways) that my SO creates profiles on different dating sites or affair sites and/or answering CL ads. This had been an issue before, and we ended up separated and he apologized, and when I asked him why I wasn't enough, he stated 'it was not you, never you its me that has the problem'. So it stopped for a while but now becoming a problem again. But his reasoning this time is he says that I don't 'listen to him' so he creates these profiles as my punishment. As in, if we are discussing something and I 'backtalk', or if I do something against his 'rules', he goes online, does his thing, and waits for me to find it somehow or come across it so I'll be hurt by it and that's supposed to 'keep me in line'.
Is it just me or is this crazy??

He's an arrogant prick.

Your SO is totally crossing the line. Unless both parties have agreed beforehand that the relationship is non-monogamous, there's no reason for that kind of behaviour. Furthermore, mentally and emotionally "punishing" someone is a form of abusive behaviour.

You are definitely not crazy to feel that this is a problem. I rarely ever suggest this, but were I in your position, I'd give some very serious thought to ending that relationship immediately.

I would seriously consider this. You deserve better than that.

It is insulting and hurtful. What do you like about him?

This is completely beyond appropriate. I have been victim of this twice. The first time actually extended to meeting some of these women off-line. In my current relationship I have indicated this is a 'deal-breaker'. I suggest you do the same.

Whoa this is a huge red flag. This guy is arrogant and his actions are completely inappropriate. These behaviours are inexcusable. There is no reason for him to be cheating on you. He's just creating excuses to cheat on you. He's not a faithful guy.

Please reevaluate this relationship. Tread safely, honey.

Oh hell no....

(Abusive Prick Alert)

Even if you HAD a mutually agreed upon relationship of the sort you're alluding to, this is NOT the way he should be doing things. No, no...

i feel sorry for you, why do you stay with this jerk?

Gee what an a...hole. Don't have unprotected sex with him. He is likely sleeping around or is about to

He sounds like he fits the classic profile of a sex addict. Has he had this diagnosis yet? Characteristics of sexual addiction here. Ten Types of Sex Addiction here.

It sounds like your significant other's sex addiction falls under transactional sex addiction, due to the power and risk involved:

Trading sex: Using sex as part of a business transaction. This is addictive because of the risk, cost, or repetition of early trauma

Paying for sex: Purchasing sex as in compulsive prostitution or phone sex services

Shyt human being....walk , no ... Run away.

Mentally abusive,(I don't use that term often, even here.)
Manipulative.
Vindictive
Control freak.
Oh...And all round douche bag.
See the above post for appropriate action. ^^

Odd Views you say?

More like Assholian views, please take yourself off the "For Sale" rack, you're worth way more than you're giving yourself credit for.

You deserve SO much better than the moldy crumbs this creep is feeding you.

Why do you even feel the need to ask?
