He’s commenting on other girls pictures while in relationship and it’s bugging you; this isn’t a matter of questioning whether you should bring it up to him or not, the automatic answer would be to ask him why he’s doing these things while he is in a relationship with you. If commenting on other girls picture is a deal breaker to you, I have no idea why you’re putting up with it.

Talk to him and tell him how it’s making you feel so that he cannot do it again. If he refuses the at least you know where you both stand in the relationship.

True, I guess it's not so much a deal breaker, it's just odd, because it's so suddenly random.

He’s complimenting girls and not you. This seems dodgy, no matter who the guy is, this should never happen unless it’s been initiated or accepted that there’s nothing internally going on that you don’t know about /or you both have agreed that you can comment on other people’s appearance.

He’s commenting on other girls pictures deliberately, complimenting them, adding heart eyes emojis, it just seems to me that he has absolutely no respect for you. It’s obviously getting to you, the best thing would be to talk to him even if it’s random. If he doesn’t understand then you both know where you stand. This isn’t normal for someone to go through considering you’ve also been cheated on twice in the past; at the end of the day, you should always put your mental health before others!!!

Thank you and true. It's also odd as he isn't the type to do it deliberately either, as least I don't think he would, but we dud agree that we shouldn't be commenting on other people's appearances. How would I start the text, asking him about it? For most of my life, I have really struggled with friendships too, often being bullied/excluded out. He knows all about that and people cheating on me in the past. I love him so deeply too, as despite him commenting on other girl's posts, girls of which I know, he has never even met, he often mentions how he wants a future family and marriage with me. Thank you for being so understanding of my situation too, it means a lot.

personally i wouldn’t have that and i would find it disrespectful of our relationship. speak to him

The messages seem a bit deliberate to me, if he’s complimenting girls in the presence of you, that’s even more disrespectful if he was to do it in the absence of you. He agreed on not complimenting on other girls pictures but he isn’t going with his own agreement, this is a deal breaker! He’s breaking the deal for the relationship, it’s definitely right to talk to him about it. You could go ahead and send him a text (preferably with screenshots) and ask him to explain what the comments mean. Whether or not it was deliberate, it doesn’t matter. He has realised that you’ve been cheated on, he should therefore be cautious for it not to happen again; it’s logical to think that.

Comment on fit guys pictures, hell soon stop.

Thank you so much for the helpful advice, your really nice. He did it just after I went to bed last night, saying 'I like your hair that length' (one of the two times he's commented on another girl's posts) and the other time, was two days after Valentines Day this year, with the same girl, saying 'You have the most amazing eyes'. This was on Instagram.

If it was the same girl, you could ask him who she is. Then go ahead and say that you feel that he’s getting a bit too comfortable in commenting on her pictures, and it doesn’t make you feel appreciated enough. For the love of the relationship, you would want it to stop happening and that you feel that if these comments go unnoticed, it could potentially harm your relationship in the future as things will always go away unnoticed then which will eventually lead to the relationship ending.

He did it after you went to bed, so he must’ve thought you would not have seen it, question him on why he’s done so. If there’s no clear cut answer or if he beats around the bush, you can go ahead and decide on what you want to do with the relationship.
