When someone you're in relationship with keeps liking girls pics.

Start liking guys pics. Twist it and see how he reacts on that
That would be my step after talking.

Demi read my mind.

If a guy I was seeing did those things and told me I was being jealous, I'd tell him, "Yup. And you know what? If the gander can do it, why can't the goose?" and, as Demi said, I would then proceed to "like" pictures of several guy friends and make comments about how good they looked ("Wow, dude, you must be working out! It shows!")

If the guy I was dating then proceeded to complain, I would want to know exactly why he would be allowed to do such things and why I would not be, and how far this extended (what else is he allowed to do that I am not?)

And if he still didn't understand or see things from my perspective, I wouldn't see any reason for us to be together (but that's just me.)

I hope everything out for you, Cate. Please keep us updated.

Well i had a similar situation with Martin at the beginning where he woukd watch woman and stuff that poped up on his facebook and stuff. He first had no idea why I got so upset but when I asked him if he wanted me to do the same he realised my view and stopped
If he had acted mucg different i would have left with no remorse

I have no problem with liking photos. Neither of us who are in my relationship do.
Commenting in the way you're suggesting would be a no no though.

Two wrongs do not make a right...Red Flag him and toss him to the curb......as you make a sharp left turn.

Well, I'm going to stick my well-armoured toe in this shark-infested discussion...

Frankly, the OP gives very little information, and it seems that we have filled in the details as we see fit. What is the nature of the relationship she is (was) in? How long had they been seeing each other? Had they made a commitment to date only each other? It is far too easy to assume that the relationship was much more serious than it actually was... both for the parties involved, and especially for us as anonymous observers.

Unless there was a discussion in which both parties agreed to be "monogamous", AND having learned about the man's behaviour, the lady made it clear that she wasn't comfortable with it, her complaint is unjustified. "He should just know it's wrong" doesn't fly in a world where culture and relational norms are influenced by so many often-conflicting factors.

Neither men nor women become blind when they are in a relationship. Men notice beauty. He noticed you, didn't he? If you expect a man to "only have eyes for you", you're naïve; that's very uncommon. It doesn't mean he'll drool over everything in a skirt, nor even take a second or long first glance, but he will notice. Some women in relationships notice other men... but I'm sure nobody here thinks that is okay... right?

If you have expectations about such things, be clear about them. Don't ask more of a relationship partner than is appropriate for the level of commitment you knowingly share. Be clear about things that bother you. If what you're asking is appropriate, and your partner isn't willing to abide by it, you're free to end the relationship... no shame in that. Just don't expect your partner to know something you haven't told them.

So, long story short: My friend is married to a man who does it. He has actually messaged me a few times with questionable content, which I didn't like and brought it to my friend's attention and she still married him. And, she's now seeing him doing it on open social media and his excuse is, "I'm being friendly."

So, it is a lack of respect. Sure, occasionally liking someone's photo on Facebook/Instagram is fine. I mean, I have liked someone's picture from the opposite sex before and I'm in a relationship which I'm committed to. Does that mean I'm not being faithful to my boyfriend because I liked a person's photo? Absolutely not. It's an issue when it becomes a pattern. It's a lack of respect and it makes people question the other person's faithfulness, in a way.

your in for a ride..he has a problem with lust

Not good at all.

No. They're cheating with their eyes and thoughts. And they're also cross comparing them to the lady they currently have in their life.
If they were happy to be monogamous, even in dating relationship, they would never do that. There is another thing too, if he'll lust with his eyes, you have no idea if he's being faithful with his body.

Never ever settle for less than total faithfulness, fidelity, and respect. Without those two vital characteristics in your relationship, "I love you", means nothing.

If it was me, he'd be my ex-boyfriend. The one God has in store for you isn't like that. All he see's is you. He can appreciate a pretty lady but he doesn't flaunt it in front of you like this guy is doing now. A guy can talk to women and that's not a threat to the relationship he's in with you. But a guy that comments on the beauty of other women and likes those women is flagrantly cheating.

You deserve better.
Blessings.

I would definitely not be cool with that if it was done to me, and if a guy was behaving in the same manner to my daughters I would not like it either.

No, it's not OK.

Absolutely NOT!!!! Even a pervy creep like myself knows that much

Modern Infidelity 101

Bible says flee from temptation! I wouldn’t do that but if I did and it bothered her, I’d stop right away.
