New bf follows lots of insta models & likes posts - AIBU and too sensitive?

[Pinksparkles84]

I’ve recently started seeing someone who is a few years older than me (were early 40s). I split with my husband over a year ago and we have an 8year old DS. I’m divorcing my ex husband as it turns out his a covert narc. My new bf has never married and no kids. We’ve got quite serious and see each other every other weekend (he lives about 60miles away). I went on tinder wanting to make new friends and walking buddies so wasn’t expecting to meet someone I really like. I’ve met his family (sadly he recently lost his dad, a few months before we met in December).

Anyways added him on insta and as he’s been single a while it wasn’t a biggie that he followed hundreds of insta models. Well I did the insecure thing of going on some of them and noticed he’s liked a lot of the photos (regularly and recently). I know he’s into watching porn (strangely enough I like watching porn but I’ve got a high sex drive). We’ve spoken about fantasies etc and are open about sex. I don’t know if I’m being unusual for being bothered about it. Also how do you bring it up without him knowing I’ve been stalking the people he follows. I should probably just come off insta so I don’t have the opportunity to look, ignorance is bliss and all that.

Four years ago I would have said it's no big deal. Unfortunately, I have recently separated from my partner who had a similar social circle to your new boyfriend. Cheating wasn't an issue but what was an issue is our ever dwindling sex life. And three days after separation, he was meeting a woman half his age for sex. An "old friend" he said. Figures. (I am well aware this is none of my business whom he sleeps with after separation but three days?).
Since then, I am much more cautious. I am an attractive woman in my 40s and I do not want to compete with IG models. I want a man who sees me as more than "tits and bits".

Your dealbreakers are whatever suits you. If him liking models on IG is a problem that you can't get over, then finish the relationship. I would find it immature and it would make me wary but I wouldn't necessarily finish a relationship over it.
