Social media

Am I wrong for being upset if my boyfriend is constantly liking other girls pictures on Instagram? It hurts the most in my mind because I’m big and pregnant and all of these women are skinny or have nice bodies or whatever the case is. I don’t see it completely as insecurity. I feel like if I were constantly liking guys posts he wouldn’t like it like I was trying to get someone’s attention. I find it disrespectful. Idk. What do y’all think? I told him the other day I didn’t like it and yet, he’s still doing it.
