Would you ladies be okay with your BF/SO liking inappropriate pictures of girls on IG? (Boobs, ass, etc).

I noticed my bf was liking other girls pics on IG and I told him I didn’t really like it because of the type of pictures they post. He said he wouldn’t do it again on top of deleting conversations on his dm. This was 2 weeks before the new year and last night I was looking on my IG on my followers tab and noticed that he liked a picture of his friend who was showing her entire breast just minus the nipple (her boobs are huge and fabulous btw). At first it bothered me that he liked her picture because I’m Thinking he obviously likes what he sees but what bothered me more was that he said he wouldn’t do it and then continue to do it anyway and then says I’m making it a big deal and it’s just a like and that he knows her. According to him I’m too strict and so I told him I give up and don’t care to express my feelings anymore since he’s not going to take them into consideration anyway. I don’t think I’m strict just being honest of how I feel. So the Big question is am I too strict of a GF because I asked him not to like pictures of other girls that seem inappropriate.
